Organic semiconductors are promising candidates for future applications in solar energy conversion. Recent investigations of bulk heterojunction (BHJ) semiconductors have suggested a density of states and transport mechanisms ...

We theoretically investigate the interband transitions and quantum kinetics induced by light carrying orbital angular momentum, or twisted light, in bulk semiconductors. We pose the problem in terms of the Heisenberg ...

The punctual character and random nature of the impurity positions in depletion regions lead to inhomogeneities that can significantly affect the potential intergranular barriers at polycrystalline semiconductors and, in ...

En este trabajo se realiza una breve descripción de las características de los materiales orgánicos empleados como semiconductores en dispositivos electrónicos. La electrónica orgánica es una tecnología emergente y fascinante ...

We propose a mechanism to describe spin relaxation in n -doped III-V semiconductors close to the Mott metal-insulator transition. Taking into account the spin-orbit interaction induced spin admixture in the hydrogenic donor ...

Structural characterization of nanocrystalline Al-doped ZnTe semiconductors, obtained by mechanical milling from ZnTe and Al 2O3 powders, is presented. The samples were analyzed by X-ray diffraction (XRD), scanning electron ...

We explore the impact of a Rashba-type spin-orbit interaction in the conduction band on the spin dynamics of hot excitons in diluted magnetic semiconductor quantum wells. In materials with strong spin-orbit coupling, we ...
