The Avalanche-Mode Superjunction LED [PDF]
IEEE Transactions on Electron Devices, 2017 Avalanche-mode light-emitting diodes (AMLEDs) in silicon (Si) are potential light sources to enable monolithic optical links in standard CMOS technology, due to the large overlap of their electroluminescent (EL) spectra with the responsivity of Si photodiodes. These EL spectra depend on the reverse electric field.

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
