Current Collapse Phenomenon in GaN HFETs resulting from Intentional Bulk Iron (Fe) Doping and Un-intentional Interface Traps

The Gallium Nitride-based material family has fundamental material properties which make it an attractive candidate for semiconductor device fabrication.These properties include:High saturation velocities and breakdown field strength Direct bandgap, allowing fabrication of light emitting devices The ability to form hetero-structures using aluminum or indium Large bandgaps allowing high temperature operation

Syntax Driven 2D Structure Export from 3D Structures and Extraction of 2D Volume Data Maps

This article demonstrates a new feature of TonyPlot3D. This feature enables the automated, syntax driven export of 2D structure slices from 3D structures. Also demonstrated in this article is the subsequent extraction of 2D volume data maps with regular spacing using a combination of EXTRACT commands, system commands and loops.

Leakage Current Calibration Procedures of Amorphous Silicon Thin-Film Transistors

Amorphous silicon Thin-Film Transistors (a-Si TFTs) are widely used as the switching device of liquid crystal display (LCD) technology. For development and analysis of a-Si TFTs, many research groups are trying to understand the physical mechanisms of a-Si TFTs. In particular, leakage current behavior is a major consideration for switching devices like a-Si TFTs. To analyze the leakage current mechanisms, calibration with numerical simulation is required.

3D TFT Simulation

Both flexible and touch panel displays have become popular for portable applications. To meet various functional requirements, system-on-panel (SOP) design has become essential [1] and different layouts as well as material have been used in the last few years [2]. Although various design and physical effects [3-5] have been successfully analyzed using 2D Technology-Computer-Aided-Design (TCAD) software, it becomes important to start to analyze and predict device performance dependent on layout effect with 3D TCAD.

The Studies of Anti-Reflective (AR) Coatings Effects for Solar Cell by Using Silvaco TCAD Tools

In 1975, screen printing was first applied to solar cells for the formation of the front and rear contacts replacing expensive vacuum metallization [1]. The encapsulate used in a photovoltaic (PV) module has many requirements. It must be optically transparent, electrically insulating, mechanically compliant, adherent to both glass and cells, and sufficiently robust to withstand 20–30 years in the field. Since the early 1980s, the encapsulate in all PV modules has been ethylene vinyl acetate (EVA) [2, 3].

Geiger Mode Simulation of Avalanche Photodiodes in ATLAS

Single-photon counting detectors are used in a wide range of applications, including astronomy, optical communications, biological sensors, and military uses. Photomultiplier tubes (PMTs) have fulfilled these needs in the past. Now, avalanche photodiodes (APDs) operating in Geiger mode as single-photon counters offer advantages over PMTs which include higher quantum efficiency, smaller size, and lower breakdown voltages. Geiger mode APDs have demonstrated single-photon sensitivites from the far infrared to the deep ultraviolet wavelengths.
