Dielectric function of the semiconductor hole gas
The semiconductor hole gas can be viewed as the companion of the classic interacting electron gas with a more complicated band structure and plays a crucial role in the understanding of ferromagnetic semiconductors. Here we study the dielectric function of a homogeneous hole gas in zinc blende III–V bulk semiconductors within random phase approximation with the valence band being modeled by Lut...
متن کاملDielectric confinement of excitons in type-I and type-II semiconductor nanorods.
We theoretically study the effect of the dielectric environment on the exciton ground state of CdSe and CdTe/CdSe/CdTe nanorods. We show that insulating environments enhance the exciton recombination rate and blueshift the emission peak by tens of meV. These effects are particularly pronounced for type-II nanorods. In these structures, the dielectric confinement may even modify the spatial dist...
متن کاملExcitons and the lifetime of organic semiconductor devices.
While excitons are responsible for the many beneficial optical properties of organic semiconductors, their non-radiative recombination within the material can result in material degradation due to the dumping of energy onto localized molecular bonds. This presents a challenge in developing strategies to exploit the benefits of excitons without negatively impacting the device operational stabili...

متن کاملIncluding excitons in semiconductor solar cell modelling
Excitonic effects are introduced in standard semiconductor device modelling of solar cells. Previous work by the groups of Green and of Zhang is extended here to also include field dependent exciton dissociation in the space charge layer (SCL) of a np diode, and exciton surface dissociation or charge transfer at the contact or at the junction. A clear result is that it is possible to apply the ...
