Systematic Synthesis of Organic Semiconductors with Variable Band Gaps
Band Gap Isothianaphthene Organic Photovoltaics Polythiophene Semiconducting Polymers Thieno[3 4 b]thiophene
2014/11/21
Polymeric materials are attractive candidates for the fabrication of low cost, large area photovoltaic devices. Controlling the band gap of the electroactive polymer is an essential factor in optimizi...

The research presented in this dissertation focuses on the design and synthesis of novel hybrid conjugated polymer materials using two different approaches: 1) inorganic/organic hybrid semiconductors ...
Mid-IR-laser microscopy as a tool for defect investigation in bulk semiconductors
Mid-IR-laser microscopy defect investigation bulk semiconductors
2011/9/9
A non-destructive optical technique described in this paper is an effective new tool for the investigation of defects in semiconductors. The basic instrument for this technique—a mid-IR-laser microsco...
Optical beam-induced scattering mode of mid-IR laser microscopy: a method for defect investigation in near-surface and near-interface regions of bulk semiconductors
Optical beam-induced scattering mode mid-IR laser microscopy
2011/9/9
This paper presents a new technique of optical beam-induced scattering of mid-IR-laser radiation, which is a special mode of the recently developed scanning
mid-IR-laser microscopy. The technique in ...
Superconductivity in compensated and uncompensated semiconductors
superconductivity semiconductor localization diamond
2010/10/12
We investigate the localization and superconductivity in heavily doped semiconductors. The
crossover from the superconductivity in the host band to that in the impurity band is described
on the basi...
Spin drift and spin diffusion currents in semiconductors
semiconductor drift-diffusion electrical properties spintronics
2010/10/12
On the basis of a spin drift-diffusion model, we show how the spin current is composed and
find that spin drift and spin diffusion contribute additively to the spin current, where the spin diffusion ...
