THz Spectroscopy Characterization

The TNL-TS (THz Spectroscopy) Simulator is a powerful tool for simulating the dynamics of charged particles interacting with THz phonons. Individual particle motion under THz pulses, characterize the HOT carrier conductivity including non-linear scatterings from impurities and lattice vibrations, disrupting charge carrier momentum and energy. Stochastic modeling effectively characterizes charge carrier transitions in bulk and nanomaterials. The Monte Carlo method, used to solve the Boltzmann transport equation under THz pulses from hundreds of gigahertz to several terahertz. The simulator can also model the microscopic conductivity of weakly confined classical electrons without needing approximations or fitting parameters.

The TNL Terahertz (THz) Spectroscopy Simulator is a unique tool for simulating material properties under electromagnetic fields from terahertz pulses. It provides a flexible approach to resolving and controlling individual carrier transitions among many-body states, enhancing understanding of atomistic and quantum kinetics and advancing technologies at the quantum level.
