Control of a Four Level Active Gate Driver for SiC MOSFET

Denne masteroppgåva presenterer utforming, simulering og implementering av kontroll for ein styrekrins for silikon karbid metall-oksid-halvleiar felteffekttransitor (MOSFET). Styrekrinsen nyttar mellombelse spenningsnivå som kan justerast i både amplitude og lengd. Dette er for å forbetra kontrollen av MOSFETen.

A Highly Robust Integrated Gate Driver Based on Organic TFTs for Active-Matrix Displays

IEEE Journal of the Electron Devices Society
A highly robust integrated gate driver based on organic thin-film transistors (OTFTs) is proposed that effectively addresses the output degradation caused by depletion-mode operation, instability and variation.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance
