Sergei Baranovski - Disorder effects in semiconductors: known unknowns and fundamental scales 

Topics: Fundamental spatial scales of disorder in amorphous organic and inorganic semiconductors as well as in doped crystalline semiconductors; fundamental spatial and energy scales of disorder in semiconductor alloys; fundamental scales of disorder for charge recombination in amorphous inorganic semiconductors.

Marcel Filoche - Disorder computations through landscape localization I & II

Topics: concepts of the landscape localization (LL) theory and application to semiconductors: Mathematical theory of LL; basic properties of the landscape function u and its inverse W; approximations of energy, wavefunction and its decay (Agmon distance); approximations of energy, wavefunction and its decay (Agmon distance)

Simone Fratini

Sergey Karpov - Semiconductor device simulation I & II

Topics: elements of inorganic device simulation: Poisson Drift diffusion model; ABC recombination model; p-n junction; heterojunction; finite element methods; application to nitride semiconductors (the SILENCE software).

Erich Runge

Stefan Schulz

Claude Weisbuch - Introduction to basics of semiconductors I & II

Topics: energy bands, electrons/holes, effective mass approximation (EMA), doping, absorption/recombination, heterostructures/quantum wells, carrier drift/diffusion. Application to nitride semiconductors: internal electric field effects; potential map with disorder in the EMA.

Bernd Witzigmann
