Crosslight is proud to announce new features & milestones for its upcoming v2022 release. In addition to multiple bug fixes and improvements, the following new feature/improvements were made:

• VCSEL model for multiple tunneling junctions has been improved so that more accurate optical output can be extracted from the simulation.
• Significant improvements in speed, accuracy, and ease of use for the microcavity FDFD model. This model is now recommended for complex VCSEL structures, including devices with multiple tunnel junctions.
• Hot carrier injection/trap generation model for thin film transistors.
• Updated AC models.
• New 3D mesh generation system.

This version will be released later this year, after final testing has been completed. Customers with an up-to-date maintenance contract can contact their local sales representatives if they wish to try these new features right away.

We are proud to announce the fourth annual winner of a collaboration with Assistant Professor Can Bayram of the University of Illinois at Urbana-Champaign. As part of this collaboration, students worked with Crosslight TCAD tools in an academic setting and the best projects were selected for a prize.

Congratulations to the 2022 winners of this award:

• Jaekwon Lee for 2D Optical-Thermal-Electrical Simulation for High Wall Plug Efficiency Cubic GaN Green LED on Silicon
• Robert Kaufman for HgCdTe Long-Wave Infrared Photovoltaics for Directed Energy Applications

A new presentation on our microcavity model has been added to our Laser Diodes application page.

A copy of a talk given at the CASICON2021 conference by our CEO and founder, Dr. Simon Li, has been uploaded to our Miscellaneous Conferences page.

A new presentation on how to convert existing VCSEL input files from a scalar model to a full vectorial solution has been posted to our Laser Diodes application page.

Crosslight is proud to announce new features & milestones for its upcoming v2021 release. In addition to multiple bug fixes and improvements, the following
new feature/improvements were made:

• LINUX platform release Process and Device simulation with improved GUI support
• Metal/semiconductor interface to support the same metal in contact with multiple regions of semiconductor
• Hot carrier injection model implemented using hydrodynamic TCAD simulation to support modeling of long term reliability related to hot carrier injection in transistors
• Hydrogen and other impurity diffusion common in TFT process
• Interface between LTSpice project files and mixed-mode TCAD simulation, so that it is convenient to start with a LTSpice simulation when adding circuit elements to TCAD simulation.
• Field-induced trap emission (Poole-Frenkel) model
• VCSEL/TMM model improved to handle tunnel juction cascade MQW VCSEL
• Special treatment minority carrier in wide bandgap materials enhanced to improve convergence
• Mesh-bending model improved to treat TFT-OLED with multiple cells

This version will be released later this year, after final testing has been completed. Customers with an up-to-date maintenance contract can contact their local sales representatives if they wish to try these new features right away.
