Physics of Thin-film Deposition

Thin-film coating processes are ubiquitous across the scientific world. They have historically been used to design optical cavities, coatings for SEM and give materials useful cosmetic or practical properties. More recently, they are gaining ground in the world of solid state batteries and thin-film perovskite solar cells. Join us for an overview of thin-film deposition techniques, including PVD, CVD, roll-to-roll coating and much more.

HEX Online User Meeting

Join the Korvus team and two invited speakers to learn the key fundamentals of the HEX. The meeting will consist of two presentations from existing users on their applications and experiences, each of which will be followed by a detailed Q&A session. Afterwards, there will be a training presentation from one of the Korvus Technology team. This meeting is not just for HEX users, but for the users of other PVD systems and those generally interested in the technique.

 

First Speaker: Dr Bruno Rente, Imperial College London

Talk Title: “Deposition of metals and metal oxides using the HEX systems”

Dr Bruno Rente is the Research Facility Manager for the Royce Institute at Imperial College London. He is a specialist in thin films and nanofabrication and will talk about the long-term usage of the HEX and HEX-L systems at Imperial College London. Bruno received a degree in electronic engineering from the Federal Centre for Technological Education, Rio de Janeiro, Brazil, in 2010, a master’s degree from the Brazilian Centre for Research in Physics, where he gained experience with instrumentation and photonics, and a Ph.D. degree from the Federal University of Rio de Janeiro in 2017.

Bruno worked as a Laboratory Engineer for the Metallurgy and Material Department, Federal University of Rio de Janeiro. In that occasion, his work was focused in photonics and materials for chemistry, optics, and tribological applications. He was a Postdoctoral Research Fellow with the City University of London working with fibre optic sensors for harsh environment applications.

He holds a post as Lecturer of the Federal Centre for Technological Education, Rio de Janeiro in the field of Instrumentation and Electronics and is currently the Research Facility Manager for the Royce Institute at Imperial College London, supporting researchers on material science and device manufacturing including photonic, plasmonic and electronic devices.

 

Second Speaker: Dr Andrea Vezzoli, University of Liverpool

Talk Title: “Single-Molecule Electronic Devices: Integrating Mechanical Functionality at the Nanoscale”

Dr. Andrea Vezzoli is a Royal Society University Research Fellow and a Reader in Physical Chemistry at the University of Liverpool.

His work focuses on the fabrication of functional single-molecule junctions – extremely small nanoelectronic devices made by one molecule “chemically soldered” to two nanoelectrodes. He has developed single-molecule transistors, nanoelectromechanical devices, and optoelectronic diodes, establishing structure-property relationships and developing novel instrumentation for high-bandwidth measurements. His group works on all aspects of junction fabrication, from the design and synthesis of molecular wires to their nanofabrication and nanomanipulation into single-molecule junctions, and the characterisation of their optoelectronic properties.

In addition to support from the Royal Society, Andrea’s research is also in receipt of council funding (EPSRC New Investigator Award 2020, EPSRC Core Equipment Award 2021, ERC Starting Grant 2022) and he sits on the management committee of the nanofabrication suite at the University of Liverpool with colleagues in Physics and Engineering.

 

Third Speaker: Dr Jessica Stoner, Korvus Technology

 

Dr. Jessica Stoner is the Product Manager for the HEX series at Korvus Technology.

Before joining Korvus in 2021, Jess worked as a researcher at the Materials Innovation Factory at the University of Liverpool. She worked on the synthesis and characterisation of functional thin films deposited using the PVD method, pulsed laser deposition.

Since joining Korvus, Dr. Stoner has installed a multitude of different HEX and HEX-L systems, and is directly involved with research and development to expand the company’s product line. She manages all technical aspects of the HEX both behind the scenes and in direct contact with users new and old, helping them to properly operate these PVD devices to achieve the best results possible.

Sputtering in PVD

Sputter deposition is a physical vapour deposition (PVD) method of depositing thin films by sputtering material from a ‘target’, then depositing it onto a ‘substrate’. Magnetron sputtering applies a magnetic field around the target in order to energize argon atoms for bombarding the target.

The Fission magnetron sputtering source enables rapid, contaminant-free deposition of metal or dielectric films in the HEX modular deposition system. Water-cooling and gas connections are made using quick-release connectors, removing the need for specialist tools to dismount the source and eliminating the hazard and inconvenience of draining coolant-water each time the source is removed from the chamber. Source mounting is also efficient and simple, without the need for specialist tools.

The Fission source can be operated in DC mode for conducting materials and RF mode for insulating materials. Gas introduction is through the gas hood, allowing a higher partial pressure to be achieved near the target surface and thereby reducing the overall chamber pressure required during deposition. The source can be equipped with manual or motor-driven shutters and can be controlled using our PC automation option.

Reactive sputtering can be enabled either by introducing additional gases directly with the sputtering gas or with a separate gas feed in the chamber. Magnetic materials can be sputtered using an optional strong magnet set which allows targets up to 1mm thick to be sputtered. The Fission source can be used to sputter all (solid) metals, insulators and semiconductors. Multiple sources may be used in one system in order to grow multilayer or composite material films.

Join the Korvus team to discuss the technical details of different sputtering techniques and processes, including: DC, RF, HiPIMS, Pulsed-DC and more…

Advancements in Physical Vapor Deposition (PVD) for Battery Research

Physical Vapor Deposition (PVD) is used industrially for depositing nanometers-to-microns of a material to produce functional layers/alter surface properties. The technique is paramount in pioneering the development of solid-state/lithium-ion batteries.

Key solid-state challenges are impedance at the cathode-electrolyte interface, volumetric energy density, and dendrites/crack formation during cycling. PVD is ideally suited to manufacturing promising solutions, whilst allowing high-throughput screening of novel material compositions to enhance electrochemical properties.

The HEX is a cost-effective system, mountable beneath an existing glovebox for fully inert development. The unique configuration maximizes glovebox space and enables easy atmosphere-side modification/cleaning. The high modularity facilitates changes without specialist tools, enabling rapid changes in research approach without additional costs. Integration of sputtering/thermal/e-beam/organic evaporation/substrate heating allows extensive material production capabilities.

 

This webinar will focus on the following key topics:

• PVD techniques used to produce functional layers/alter surface properties

• Development of model systems to study interfacial phenomena

• High throughput screening of novel materials to enhance electrochemical properties

• Introduction to the HEX series of PVD instrument and its key advantages for research, including unique mounting position below the glovebox
