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.
