What's new in tiberCAD 2.5

Built-in Atomistic generator

  • Allows to generate an atomic basis associated with the finite element mesh which belongs to a given physical region, based on the material specifications and the growth directions defined for that region

  • Supports any crystal structure with fcc, bcc, cubic and hexagonal Bravais lattice

  • Performs hydrogen passivation for any crystal structure supported

Valence Force Field (VFF) module for atomistic-based structure relaxation

Empirical Tight Binding (ETB) module

  • Atomistic-based calculations of electronic and optical properties of Nanowires, Quantum Dots and Quantum Wells

  • Accurate ETB sp3s*d parameterization for several material, including GaN/AlGaN/InGaN systems

  • VCA and random alloy approach to treat in a fundamental way nanometric features in active regions, such as alloy fluctuations. Random alloy representations provide a realistic picture of a nanostructured LED active region

Models for transport in organic devices in Drift-Diffusion Module

  • Gaussian Density of States (DOS)

  • Hopping mobility model
