General Research Interests
Semiconductor nanocrystals: Mechanical, optical and electrical properties of ion beam generated Ge and Ge-Sn nanocrystals embedded in silica.
Semiconductor crystal growth: Liquid phase homo-epitaxy of ultra-pure GaAs on semi insulating and doped GaAs; and of ultra-pure and doped Ge; Czochralski growth of ultra-pure and doped Ge crystal of natural and isotopically controlled composition.

Semiconductor characterization and processing: Electrical (variable temp Hall effect and resistivity), Deep level transient spectroscopy (DLTS)), optical (far IR spectroscopy with Fourier transform spectrometers, mid- and near-infrared, visible and UV grating spectrometers, photoluminescence) and ion beam characterization (Rutherford backscattering spectrometry RBS) of dopants, impurities and native defects.

Far infrared lasers and detector; low temperature thermal sensors: Research and development of semiconductor hole population inversion THz lasers, low background far infrared photoconductors and pyroelectric detectors, neutron transmutation doped Ge thermistors and thermistor arrays operating down to 10 milli Kelvin for a wide range of solid state, astrophysical and cosmological studies.

Isotopically controlled semiconductors: Studies of a broad range of properties and effects which are influenced by the isotopic composition of semiconductors.
