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 ...

On the Dynamic Performance of Laterally Gated Transistors

Elison de Nazareth Matioli, Armin Jafari, Catherine Erine, Giovanni Santoruvo

Laterally gated transistors have been proposed as an innovative device architecture in which a semiconducting channel is controlled by side gates. In this sense, the gate can either be in contact with the sidewalls or be separated by a gap. In the latter c ...
