Normally-OFF Diamond Reverse Blocking MESFET [PDF]
Schottky contacts have been used to fabricate normally-off lateral reverse-blocking MESFETs on p-type (boron-doped) O-terminated monocrystalline diamond. The devices utilized an ohmic source contact but both gate and drain contacts were Schottky in nature.

Normally-off GaN Transistors for Power Applications [PDF]
Normally-off high voltage GaN-HFETs for switching applications are presented. Normally-off operation with threshold voltages of 1 V and more and with 5 V gate swing has been obtained by using p-type GaN as gate. Different GaN-based buffer types using doping and backside potential barriers have been used to obtain blocking strengths up to 1000 V.

Breaking Through the Multi-Mesa-Channel Width Limited of Normally Off GaN HEMTs Through Modulation of the Via-Hole-Length [PDF]
We present new normally off GaN high-electron-mobility transistors (HEMTs) that overcome the typical limitations in multi-mesa-channel (MMC) width through modulation of the via-hole-length to regulate the charge neutrality screen effect. We have prepared

Technology and Reliability of Normally-Off GaN HEMTs with p-Type Gate
GaN-based transistors with p-GaN gate are commonly accepted as promising devices for application in power converters, thanks to the positive and stable threshold voltage, the low on-resistance and the high breakdown field.

Cointegration of normally-off and normally-on high frequency GaN HEMTs
Dans le cadre de la fabrication de dispositifs hyperfréquences, la fonctionnalité normally-off présente deux avantages : elle permet d’une part de s’affranchir de la source de tension négative pour les circuits intégrés monolithiques hyperfréquences (Monolithic Microwave Integrated Circuit – MMIC) et, d’autre part, la co-intégration de transistors ...
