Latest Software Updates
PL in SiLENSe 6.4
SiLENSe version 6.4 has been released. Simulation of PL is updated in such a way that generated carriers are included into the main drift-diffusion computations. As users can specify the p-n junction bias together with PL excitation, PL simulation can predict the photocurrent and can be used for simulation of photodiodes and single-junction solar cells.
VR 8.2 for PVT SiC
VR-PVT SiC has been updated. New features include automatic switching between phases in the powder source (pure carbon, graphitized SiC with simultaneous coexistence of SiC and carbon, or pure SiC), programmable variation of argon/nitrogen ratio in the gas, improved boundary shifting procedure in long-term growth.
Intrinsic Carbon Doping
Unintentional carbon incorporation during MOCVD growth of GaN can now be considered in the whole family of STR software tools for modeling of epitaxy. The model can be applied to different reactor types and wide rang of process parameters, such as temperature, pressure, TMGa flow rate (growth rate), V/III ratio, and carrier gas composition. Modeling can be used both to find process parameters suitable to achieve a required doping level and to adjust the carbon concentration uniformity over large wafers.
Faster Problem Specification in Flow Module 3D
CGSim 21.0 has been released. New tool added in Flow Module 3D makes problem setup at least 4 times faster by facilitating the transfer of the hot zone geometry along with computational mesh and material properties from Basic CGSim to Flow Module.
New Version of SiLENSe
SiLENSe Version 6.3 has been released. It is a major update of the software including advanced models for material properties and a new solver with improved speed and convergence.
Tri-Halide VPE of GaN
Chemical model for simulation of THVPE has been added in HEpiGaNs software. Simulation of two-chamber source of GaCl3 is supported.
SpeCLED & RATRO Update for Micro-LEDs
SimuLED software had a major update, namely, new SpeCLED & RATRO modules with capabilities enabling simulation of micro-LEDs were released. Improvements include new solver in RATRO.
Virtual Reactor 8.1 Released
A new version includes new features for modeling of both epitaxy and bulk crystal growth.
