TiberCAD is a project of the Opto&Nanoelectronics group aiming to combine the expertise acquired in device simulations for the realization of an integrated Multiscale TCAD.

Features available in version 1.2.2

From May 13rd, 2009 TiberCAD v. 1.2.2 will be available for download

New features

  • Auger recombination
  • surface recombination for interface boundary model
  • self consistency Schroedinger-Poisson/Drift Diffusion based on predictor-corrector scheme with embracing region
  • physical models can be restricted to a subset of the simulation domain
  • string labels can be used in GMSH as physical region identifiers instead of numbers
  • more meaningful error messages from input parser

 

Features

TiberCAD is a multiscale CAD tool for the simulation of modern nanoelectronic and optoelectronic devices. Possible applications of TiberCAD range from nanoelectronics  to laser technologies including molecular electronics and bio-devices.
The tool is currently under intense development. Here is  a  brief  description of  the features of  TiberCAD project.

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, classical, atomistic and 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 behaviour.

Physical models:

  • Strain/stress modelization, including pyro- and piezoelectric effects, non-linear strain, converse piezoelectric, external forces
  • Classical (Drift-Diffusion, hydrodynamic) particle transport and  Poisson
    calculation, Quantum Current calculation (quantum drift-diffusion,
    Non-Equilibrium Green Function)
  • Electrons, holes and excitons dynamic
  • Heat balance model: electron and  hole  dissipation, microscopical  heat  model
  • Quantum physics for  continuous media, including Envelope  Function Approximation, k.p theory.
  • Atomistic quantum description, including Empirical Tight-Binding model and ab-initio methods
  • Electromagnetic solver for optical fields

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)

 

A  free trial version of TiberCAD  is now available for download.


Please note  that   not  all  the  features  of  the full  Tibercad  package  suite  are  available  in this  trial  version.
The  first  commercial  release of  Tibercad will be  issued  soon. (see http://www.tiberlab.com)
