logo tiberCAD - multiscale simulation

tiberCAD is a multiscale tool for the simulation of modern nanoelectronic and optoelectronic devices.
Applications of tiberCAD range from nanoelectronics to laser technologies including molecular electronics and bio-devices.

In the following, a short list of the main features of tiberCAD:

Structure/device editor:

  • Tools for creating geometric structures for TCAD simulation, including an extensive material database
  • 1D/2D/3D modeling and meshing (structured and not ), cylindrical symmetry, adaptive mesh refinement
  • support for external meshing tools (ISE-TCAD, Silvaco)
  • built-in atomistic structure generation tool: coupling to the geometric model, several crystal lattices (cubic, hexagonal, fcc, bcc), hydrogen passivation model

Multiscale approach:

Quantum and  classical continuous descriptions can be used in different regions of a device/nanostructure within the same simulation; analysys and optimization may be performed at all the relevant scale lengths, possibly including self-consistent coupling of different models, such as quantum/drift-diffusion, thermal/drift-diffusion.

Physical models:

  • Strain/stress modelization, including pyro- and piezoelectric effects, non-linear strain, converse piezoelectric, external forces
  • Classical (Drift-Diffusion) particle transport and Poisson calculation
  • Electrons, holes and excitons dynamic
  • Heat balance model
  • Quantum physics for continuous media, including Envelope Function Approximation, k·p theory


Device applications:

  • Electronic devices analysis and design (HEMT, MOSFET, BJT,etc)
  • Nanoelectronic devices (nanoMOSFET, CNTFET, nanowire etc.)
  • Molecular and Organic electronics devices (OTFT, OLED, OPV)
  • Optoelectronic Devices (LASER, LED, Photodetectors)
  • Solar Cells (silicon based, CdTe, CIGS, DSSC, organic)
  • Nanostructures (quantum wells, quantum dot, III/V heterostructures)
