  1. Phonon modeling in zinc-blende semiconductorsAbhijeet Paul and Gerhard Klimeck Objective: Phonon modeling in zinc-blende semiconductors for the calculation of thermal properties. Result: Approach: Modified VFF potential energy (U)  Dynamical matrix + boundary conditions  Phonons. UMVFF = Ubb+Ubs+Ubb-bb+ Ubb-bs+Ubs-bs bb = bond-bending, bs = bond stretching Impact: (1)Good match with experimental bulk data. (2) Method extended to free-standing nanowires. Bulk Si Benchmarking of phonons in bulk Si. Experimental data from: G. Nilsson and G. Nelin, Phys. Rev. B, 6 (10), 1972.
