On-Chip High-Voltage Sensors Based on Trap-Assisted 2DEG Channel Control

Elison de Nazareth Matioli, Armin Jafari

In this work, we present a new device concept for compact high-voltage sensing with high-impedance input port, consisting of an AlGaN/GaN high-electron-mobility channel controlled by trapped carriers generated by a metallic electrode. The high-voltage appl ...

A Low-Power Microwave HEMT $LC$ Oscillator Operating Down to 1.4 K

Giovanni Boero, Nergiz Sahin Solmaz, Alessandro Valentino Matheoud

High-electron-mobility transistors (HEMTs) based on 2-D electron gases (2DEGs) in III-V heterostructures have superior mobility compared with the transistors of silicon-based complementary metal-oxide-semiconductor technologies. The large mobility makes th ...

High-Voltage Normally-off Recessed Tri-Gate GaN Power MOSFETs With Low on-Resistance

Elison de Nazareth Matioli, Jun Ma, Luca Nela, Catherine Erine, Minghua Zhu

In this letter, we present normally-off GaN-on-Si MOSFETs based on the combination of tri-gate with a short barrier recess to yield a large positive threshold voltage (VTH) while maintaining a low specific on resistance (R ON,SP ) and high current density ...

1200 V Multi-Channel Power Devices with 2.8 Ω•mm ON-Resistance

Elison de Nazareth Matioli, Jun Ma, Catherine Erine, Minghua Zhu, Kai Cheng

Here we report novel multi-channel AlGaN/GaN MOSHEMTs with high breakdown voltage (V BR ) and low ON-resistance (R ON ). The multi-channel structure was judiciously designed to yield a small sheet resistance (R s ) of 80 Ω/sq using only four 2DEG channels, ...

Ultrathin Junctionless Nanowire FET Model, Including 2-D Quantum Confinements

Farzan Jazaeri

In this paper, we develop an explicit model to predict the dc electrical behavior in ultrathin surrounding gate junctionless (JL) nanowire field-effect transistors (FETs). The proposed model considers 2-D electrical and geometrical confinements of carrier ...
