Phonon-mediated Migdal effect in semiconductor detectors

Semiconductor Detectors in Radiation Medicine:

Semiconductor radiation detectors play an important role in radiation instrumentation. They have many advantages due to their small size, outstanding energy resolution in nuclear spectroscopy, easy pixilation for high spatial resolution and ability of integration with readout electronics. Advancement in microelectronic industry made silicon one of the most popular material for radiation detecto...

Semiconductor Detectors - an Introduction

Microstructured semiconductor neutron detectors

Perforated semiconductor neutron detectors are compact diode detectors that operate at low power and can be fashioned to have high thermal neutron detection efficiency. Fabricated from high-purity Si wafers, the perforations are etched into the diode surface with ICP-RIE and backfilled with LiF neutron reactive material. The intrinsic thermal neutron detection efficiency depends upon many facto...

Phonon heat conduction in a semiconductor nanowire

A model for phonon heat conduction in a semiconductor nanowire with dimensions comparable to the phonon mean free path is developed. It is based on the solution of Boltzmann’s equation, which takes into account i modification of the acoustic phonon dispersion due to spatial confinement, and ii change in the nonequilibrium phonon distribution due to partially diffuse boundary scattering. Numeric...
