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, 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
  
• 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 including many of these features is available for download.
A commercial release of the full Tibercad package will be issued soon.
