Take a look at my biography.

Take a look at my publications.

You can find my dissertation here.

Most of my current work in the Klimeck group is dedicated to NEMO5.

This is a general purpose highly parallelized simulator for Boson and Fermion transport and bandstructure on multimillion atom devices.

So far this work includes the following topics

  • General tight-binding Hamilton constructor (arbitrary number of basis orbitals, arbitrary range of two-center interaction)

  • General surface passivator (arbitrary geometries, crystal symmetries and orientations)

  • General electronic strain Hamiltonian for tight-binding representations

  • General Schroedinger/Poisson simulator (in close cooperation with M. Povolotskyi and S. Steiger)

  • Multi-purpose NEGF-solver (for Bosons and Fermions in arbitrary - stationary and nonstationary - representations, including incoherent scattering)

  • Concept development for the general MPI-parallelization (supporting S. Steiger)

  • Concept development for the generalized recursive Green's function solution (supporting H. Park)

  • Concept and method development for efficient recursive surface Green's function solver for completely arbitrary leads

  • Concept and method development for the general low rank approximation (supporting PhD students L. Zeng and Y. He)

  • Concept and method development for realistic device surface treatment in tight-binding (supporting PhD students G. Hedge and Y. Tan)

  • Concept and method development for quantum transport simulation in thermoelectric nanodevices in the nonlinear transport regime (support of PhD student A. Paul)

  • and more to come...
  • To some minor extend, I continue my work on terahertz quantum cascade lasers (THz-QCLs) which I originally started in the group of Prof. Vogl (TU-Munich, Germany)

    Recently, I have developed a novel THz-QCL design which shows promising laser performance<\p>

    My work on THz-QCLs includes cooperations with experimental and theoretical groups of TU-Vienna (Austria), TU-Munich (Germany), Nanyang Technology Univ. Singapore, and Univ. Tokyo (Japan)
