Two new TFT presentations have been posted to our Misc. Microelectronics page. The first is an update on our existing hysteresis models while the second shows our models for hydrogen ion diffusion.

Crosslight is proud to announce new features & milestones for its upcoming v2020 release:

• FDFD optical solver upgraded to include
  • 3D vectoral eigen mode solver in Cartersian coordinates
  • Waveguide & free space propagation solver
  • Microcavity mode solver
• FDFD perturbation model implemented to improve accuracy of
  multi-mode vectorial simulations without incurring the cost of a full
  solution of the Maxwell equations at all bias steps.
• New mesh system with zero heterojunction gap model implemented.
  Previous/classic mesh model were based on material separation at a
  molecular scale.
• DLL interface for QCL devices released to users wishing to
  include their own physical models related to tunneling and
  scattering time models.
• Numerous minor bug fixes and upgrades including:
  • More flexibility in controlling how frequent the optical solver is called in a scan.
  • More bias dependent output variables.
  • Scan function control according to data file data.
  • Scanning of optical layer thickness to see the effect of optical phase change.
  • Import/export to Maxmode FDFD module.
  • For PD/solar cell, more flexible light incident options.
  • Gaussian type of gain broadening implemented in addition to Lorentzian, Landsberg, and sech().
  • Off state/reverse junction leakage, dark current model upgrade to improve accuracy of simulation at small currents.

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.

A new presentation on 3D VCSEL simulation using the microcavity model has been uploaded to the Laser Diodes application page.

A new presentation on Micro-LEDs has been uploaded to the LED application page.

A new application note on power diode reverse recovery simulation has been submitted by our collaborator, Dr. Gary Dolny. Sample input files are included on the main power device application page for interested users.

A new presentation on TrenchMOS switching and AC characteristics has been posted to our Power Devices application page.

We are proud to announce the third 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 project was selected for a prize. This year, an additional special prize was awarded due to the winning project’s timely relevance in the fight against COVID-19.

Congratulations to the 2020 winner of this award:

• Brian Li for “A Sustainable, UV-LED Disinfection System for N95 masks in Haiti”

A new presentation on TCAD modeling of Si and SiC power devices has been posted to our Power Devices application page.

Crosslight is proud to announce a new upcoming stand-alone solver for electromagnetic applications. A demonstration of the tool’s capabilities may be found on our Advanced Physics application page.

Two new TFT presentations have been posted to our Misc. Microelectronics page. The first deals with bending effects while the second covers the effects of traps on hysteresis.
