Research interests and expertise
Our research interests and expertise cover the following areas:
- advanced nanodevices for electronics, sensors and neuromorphic circuits on the nanoscale
- advanced physical electronics at micro and nano scale, semi-classical and quantum transport (NEGF)
- 2D materials (silicene, germanene, phosphorene, etc.) and their applications in electronics
- numerical modeling and simulation - from atomistic scale to compact models for circuit simulations (Matlab, C, CUDA, Verilog)
- parallel programming and computing in heterogeneous CPU+GPU environments (C, OpenMP, MPI, BLAS, LAPACK, CUDA, Matlab Parallel Computing Toolbox)
Our group is the birthplace of three simulation packages that are in constant development:
- SPARQS - scalable parallel quantum transport code for atomistic simulations of nanodevices (C, BLAS-LAPACK, CUDA, cuBLAS, cuSOLVER, cuSPARSE, OpenMP). We are working on an MPI version that will enable self-consistent 2D and 3D simulations. Application: nanotransistors and nanomemistors with 2D materials.
- QUDEN - quantum transport code for atomistic or effective mass model simulations (Matlab, Parallel Computing Toolbox). We are working on improving the code to include dissipative transport. Applications: proof-of-concept for demanding simulations, resonant tunneling diodes, nanoribbons of 2D materials.
- MORGANA - simulator of carrier mobility in graphene and graphene nanoribbons. We are currently working on improving the model to include the influence of the Ge substrate of different crystallographic orientations.
