GreenDiamond General Assembly: London, UK, 9-10 November 2017

16 novembre 2017

UCL hosted the latest GreenDiamond General Assembly, as the project nears its second reporting period. The meeting was productive and full of enthusiam as the first diamond MOSFET chips progress through to advanced fabrication stages! Stay tuned for upcoming results and publications.

The General Assembly wasn’t all work either. The consortium had the opportunity to meet the infamous founding father of UCL, Jeremy Bentham, discover the Grant Museum and enjoy a fabulous meal and music at Sarastro in the West End. Some of the best things on offer in London!

GreenDiamond Publication Alert!

15 novembre 2017

Two partners of the GreenDiamond project, Institut Néel and G2ELab, have published a paper about comprehensive electrical analysis of metal/Al2O3/O-terminated diamond. This paper gives a full picture of the different mechanisms involved in the gate oxide leakage current and Fermi level pinning in diamond MOSCAP. This basic understanding was crucial to reach one of the main objective of the GreenDiamond project: the achievement of reliable and robust gate oxide for diamond MOSFET.

The paper is available in Applied Physics Letters October 26th 2017 (DOI: 10.1063/1.4997975).

GreenDiamond goes to Japan!

7 novembre 2017

GreenDiamond partners from Belgium, France and the UK attended the 4th French-Japanese Workshop on Diamond Devices, held at OIST in Okinawa, Japan (30th October – 1st November 2017). This was an opportunity to discuss challenges and advances in the diamond power device field with colleagues from across the world.


Thank you to Stoffel Janssens (OIST), Satoshi Koizumi (NIMS) and Julien Pernot (Institut Néel) for organising!

Warwick 2017 Diamond Conference (10-13 July 2017)

14 juillet 2017

Attendees of the annual Warwick De Beers Diamond conference were the lucky audience to a talk by Alex Pakpour-Tabrizi, GreenDiamond partner from UCL!

GreenDiamond at NDNC 2017, Australia!

1 juin 2017

Members of the GreenDiamond team have travelled to the other side of the world to present some of the work done by the consortium!

At the international New Diamond and Nano Carbons conference in Cairns (Australia), Nicolas Rouget (CNRS) gave an invited talk entitled Diamond Devices for Power Electronics and Shannon Nicley (IMEC)  and Verena Zurbig (IAF) both presented their latest work optimising the growth parameters of n-type diamond for improved electronic and crystalline quality, on of the key development milestones on the roadmap to the full exploitation of diamond’s exceptional properties for power electronics.

GreenDiamond General Assembly: San Sebastian, Spain, 11-12 May 2017

15 mai 2017

Another six months have flown by and the time for the fourth GreenDiamond General Assembly has come!

We were so busy working that we forgot to take a group photo, but here is a small portion of the consortium!

All the partners were present, including our new industrial partner Indra, replacing WinInertia. Updates were detailed to the consortium for each work package and upcoming deliverables. The project is now almost half way through and still full of energy!

Thank you to Richard Seddon and Isabel Obieta for hosting us at Tecnalia  in beautiful San Sebastian.

And on a more creative note, our very own GreenDiamond poet, Loto Oluwasayo (PhD student, Institut Néel, France) has written a short piece about his work:


My echantillon, I waited long for you to come.
When you came , my joy was to the fullest
You needed a dip to cleanse off your dirt
You enjoyed the warmth/hot bath
And with a nozzle, you were properly dried

My echantillon, in that small cylinder you rest so safe
But you needed a heat in tube to glow for value
You were changed and you never remain the same
I cherish you and to lose you I cannot imagine.

My echantillon, small but valuable
Yellowish, bluish or transparent you could be
Men long to have you but for your price.
I found you and will not let you go.

*échantillon means sample in French.

Introducing DiamFab!

19 avril 2017

DiamFab is a pre-incubation company from Institut Néel in Grenoble, France. Building on Institut Néel know-how in diamond growth and the new markets which will be opened by the GreenDiamond project, the DiamFab company provides electronic grade diamond epitaxy to laboratories or industry for the fabrication of leading edge electronic devices.

Meet the team: from left to right, Etienne Gheeraert (Scientific Expert), Julien Pernot (Scientific Expert), David Eon (Project Manager) and Gauthier Chicot (Semiconductor Expert).

Award for GreenDiamond PhD student Marie-Laure Hicks!

10 mars 2017

After Gauthier Chicot in Warsaw, GreenDiamond work received more recognition with the Hasselt Diamond Workshop Brilliant Poster Prize awarded to Marie-Laure Hicks (UCL).

Process optimisation of Al/O2 ICP reactive ion etch for patterning of single crystal diamond (100) HPHT substrates and epitaxial growths, M-L. Hicks, A. C. Pakpour-Tabrizi, R. J. Edgington, R. B. Jackman.

This is key work contributing to the development of deep etching processes for diamond device fabrication, one of the technology challenges highlighted during the power electronics panel at the Hasselt Diamond Workshop.

Hasselt Diamond Workshop 2017 SBDD XXII and Core Group Meeting

The GreenDiamond consortium gathered in Hasselt (Belgium) for a meeting of the core partners and the Hasselt Diamond Workshop SBDD XXII.

A successful check-in with the core partners, the first device test results and future samples process flows were discussed in preparation for the upcoming general assembly this May!

The consortium was then strongly represented at the Hasselt Diamond Workshop with talks and posters:

An improved diamond/Al2O3 interface for gate control diamond transistors, T.T. Pham, C. Masante, P. Muret, A. Marechal, N. Rouger, D. Eon, E. Gheeraert, J. Pernot

Stability of diamond MOS capacitors using Al203 and SiO2/Al2O3 dielectrics, M. Florentin, O. Loto , V. Zurbig , R.B. Jackman, M.L. Hicks, A. Pakpour-Tabrizi, D. Eon, J. Pernot, E. Gheeraert

Electrical characterization of diamond MIM and MOS capacitors with Al2O3 oxide, O. Loto, M. Florentin, S. Duman, D. Eon, J. Pernot, E. Gheeraert

Process optimisation of Ar/O2 ICP reactive ion etch for patterning of single crystal diamond (100) HPHT substrates and epitaxial growths, M-L. Hicks, A. C. Pakpour Tabrizi, R. B. Jackman

And finally, the Workshop was the home of two important firsts for the GreenDiamond Project. The conference held its first panel discussion on Diamond Power Devices moderated by GreenDiamond Work Package Leader Christoph Nebel (IAF Fraunhofer, Germany) and Satoshi Yamasaki (AIST, Japan) with panelists T. Makino (AIST, Japan), R.J. Nemanich (Arizona State University, USA), H. Ohashi (AIST, Japan) and GreenDiamond coordinator Etienne Gheeraert (Institut Néel, France). The GreenDiamond Video received its World Premiere during the introductory panelist talks and followed by discussion between the panelists and the audience on the focus, priority areas, technology requirements and strategy for diamond power devices. Food for thought!
