An 8-nm-thick Sn-doped polycrystalline β-Ga2O3 MOSFET with a “normally off” operation
Applied Physics Letters, 2021Monoclinic gallium oxide (β-Ga2O3) has attracted the interest of the scientific community due to its application in power electronics. Power electronics that need to handle a high voltage often uses a “normally off” device with a positive threshold ...

Normally-off computing project: Challenges and opportunities
2014 19th Asia and South Pacific Design Automation Conference (ASP-DAC), 2014Normally-Off is a way of computing which aggressively powers off components of computer systems when they need not to operate. Simple power gating cannot fully take the chances of power reduction because volatile memories lose data when power is turned off. Recently, new non-volatile memories (NVMs) have appeared.

Demonstration of Normally-Off N-Polar GaN Deep Recess HEMT
IEEE Microwave and Wireless Technology LettersIn this letter, we report the first normally-OFF N-polar GaN deep recess high electron mobility transistor (HEMT). Utilizing atomic layer etching (ALE), followed by acid treatment, we achieved normally-OFF operation through gate recess etching on an N ...
