Current Saturation Behavior in GaN Polarization Superjunction Hybrid Diode [PDF]
physica status solidi (a), Volume 221, Issue 21, November 2024.This is the first report on the current saturation behavior observed in the forward characteristics of polarization superjunction (PSJ)‐based hybrid PiN‐Schottky GaN power diodes fabricated on Sapphire. As a result, most of the applied anode voltage is dropped across the regions immediately adjacent to the edge of the doped P‐GaN region closest to the ...

BJT application expansion by insertion of superjunction [PDF]
, 2010 In this paper, some high voltage Bipolar Junction Transistors are presented and compared in order to suggest a switch for household appliances with fully turn-on, turn-off control. For the first time, a comparative theoretical study, using 2D simulations, shows that concepts like the "superjunction" improve the static behaviour of conventional BJT ...

Micro &Nano Letters, Volume 16, Issue 2, Page 121-126, February 2021., 2021 Abstract In this paper, a new trench‐gate field‐stop insulated gate bipolar transistor (IGBT) structure having improved performances is proposed, investigated and compared with the properties of the conventional trench‐gate field‐stop IGBT. An npn structure is introduced to the gate trench in order to reduce the Miller capacitance and gate‐collector ...

Superjunction Power Transistors With Interface Charges: A Case Study for GaN
IEEE Journal of the Electron Devices Society, 2020 Recent progress in p-GaN trench-filling epitaxy has shown promise for the demonstration of GaN superjunction (SJ) devices. However, the presence of n-type interface charges at the regrowth interfaces has been widely observed. These interface charges pose

Lateral GaN Schottky superjunction diodes with buried p-GaN by NH3-MBE [PDF]
APL Electronic DevicesIn this work, we demonstrate lateral GaN Schottky superjunction diodes using a p–n–p layer structure. The lateral nature of these devices circumvents the difficulties in achieving charge balance with etch and regrowth techniques. The p–n–p layer Schottky

Low-voltage superjunction technology
IET Circuits, Devices & Systems, 2007 : The scalability of superjunction and superfield power MOSFET technologies to break-down voltage lower than 250 V is investigated. The influence of device geometry and process architecture on the switching figures-of-merit of these relatively new classes of power switches with a breakdown voltage rating of 80 V is presented. The current flow and field
