Heterostructure Design Studio

Key features and benefits

User friendly interface

 
  • Easy to learn Windows/Mac based user interface,
  • Build-in heterostructure layers and grid editor,
  • Build-in material database with convenient access to parameters. Parameters used in calculations of well-known materials are placed in database,
  • Powerful graphical plotting tools.
 

A3B5 semiconductors

  The software allows working with all A3B5 semiconductors and their ternary and quaternary alloys with zinc-blend crystal structure as layer and substrate materials. Any new material can be added.
 

Multi-band k•p self-consistent calculations

  Calculations are based on self-consistent multi-band k•p method with symmetrized boundary conditions. Matrix part of calculations are done using LAPACK library. The following models are realized:
  • Kane eight band model,
  • Luttinger-Kohn six valence band model,
  • Luttinger-Kohn six valence band with conduction band model,
  • Luttinger-Kohn four valence band model,
  • Luttinger-Kohn four valence band with conduction band model,
  • Effective mass conduction band model.
 

Main calculations parameters

 
  • Temperature,
  • External DC electric field,
  • External uniaxial stress,
  • Quantum well and superlattice model,
  • Self-consistent calculations mode,
  • Axial approximation,
  • Switch of the Hamiltonian terms.
 

Spurious solution elimination

  Spurious solution elimination mode for eight-band model1,2
 

Optical transition calculations

  Calculations of
  • momentum matrix elements,
  • dipole moments.
 

Optical absorption and gain calculations

  Calculations of optical absorption and gain in heterostructure medium
