 “Diamond technology at Ulm University”

Alberto Pasquarelli – Institute of Electron Devices and Circuits, Ulm University

07/10/2019 – segunda-feira – 14h –  SALA L649

Among all known materials, diamond is unsurpassed in terms of hardness, Young modulus and fracture strength, thermal conductivity, breakdown field and carrier mobility. Its chemical stability and biocompatibility are excellent, and its optical transparency ranges from ~250 nm to tens of microns.

Having a bandgap of ~5.5 eV, diamond is a very good electrical insulator, but when doped with boron its conductivity can be tailored in a wide range up to a quasi-metallic behavior.

Therefore, considering all properties mentioned above, diamond is a very interesting material for a variety of applications.

This lecture will describe the methods adopted at Ulm University for the synthesis of diamond thin films, our clean-room facility and finally show some of the diamond devices fabricated in the last years. A special focus will be dedicated to Microelectrode Arrays (MEAs) and the latest technological trends.
