The Material Characterization Framework includes FullBand, ElecMob & \ THz Spectroscopy Simulators).

TNL Particle Device (PD) Framework is an interactive platform for interfacing TNL's Family of Atomistic TCAD modules device characterization. It includes TNL- Monte Carlo Particle device (MCPD) 2d and 3d Simulators.

The StrViewer and TNLPlot tools are capable to handle graphical post processing.

EpiGrow

Unmatched thin film growth through real time Epi-growth Reactors condition, based on Kinetic Monte Carlo Algorithms. EpiGrow simulator is capable to handle sp3 semiconductors with Zincblende or Wurtzite phases. It may accurately predict about surface profiling (roughness), defects and strain due to lattice mismatch. The graphical user interface (GUI) feature of EpiGrow simulator makes it State of Art Simulator. It can also accurately predict the lattice constant of the monolayer.

FullBand

Full Band simulator, a unmatched simulator, is based on empirical pseudopotential method and simulates dispersion relation (E-k diagram) with the extracted lattice constant of the epi grown thin film grown by EpiGrow simulator. User may extract effective masses on parabolic and non-parabolic energy states, Density of States (DOS) and symmetry points energies on electronic full energy bands. Other relevant information can be obtained with dispersion relation diagram.

ElecMob

It simulates the mobility of carriers under external electromagnetic field. The carriers transportation dynamics inside material layer is solved by solution of 6 phase Boltzmann equation including standard scattering mechanisms under Fermi Golden rule for conservation of energy and momentum of the carrier over the different energy level in full band.

Spectroscopy

TNL Spectroscopy simulator is a unmatched and valuable tool for studying charge carrier transport under influence of Terahertz (THz) oscillating Electric pulses in bulk & nanomaterials. THz pulses can act as non-contact, ultrafast probes of interband and intraband excitations in nanoparticle ensembles and provide unique information for next generation nanomaterials engineering.

Monte Carlo Particle Device Simulator

Fastest Particle based device simulator taking into account the real time transportation of carriers under appropriate applied voltages in different Device geometrical regions. MC Particle device simulator solves Boltzmann-Wigner-Poisson equation for Advanced node devices, while users have flexibilities to uncheck the quantum confinement effects for conventional node devices. Poisson’s solution is generated over the node points of the mesh, wherever carrier transport solution is obtained using Ensemble Monte Carlo (EMC) method.

TNL Plot

TNLPlot is a graphical post processing tool use with all TNL's family of simulators. TNLPlot may operate stand-alone as well as with other design tools such as EpiGrow, FEB, HM, MCPD & Optimiser simulators.TNLPlot equipped with new capabilities based on users requirements and with interface capabilities with third party tools. Best displaying qualities curves can be produced and having the features for extraction of different physical parameters from the curves.

TNL StrViewer

StrViewer is a graphical viewer and post processing tool use to view 3D spacial arrangement of the atoms grown through EpiGrow simulator. StrViewer can accomodate million's of atoms in its plot window. It is capable to read the atomic configuration files with no limitations. StrViewer is useful tool to extract the lattice constant, defects and strain with in the grown epi monolayer. The extraction feature of StrViewer is the state of art tool as these informations can not be extracted with any kind of sophisiticated scientific instruments.
