The absorption of multiple photons when there is no resonant intermediate state is a well-known nonlinear process in atomic vapours, dyes and semiconductors. The N-photon absorption (NPA) rate for donors in semiconductors scales proportionally from hydroge ...
Wannier tight-binding models are effective models constructed from first-principles calculations. As such, they bridge a gap between the accuracy of first-principles calculations and the computational simplicity of effective models. In this work, we extend ...
Over the past 20 years, nanomaterials, such as quantum dots, nanoparticles, nanowires(NWs), nanotubes, and graphene, have received enormous attention due to their suitable properties for designing novel nanoscale biosensors. Nanomaterials are very small st ...
The invention relates to an optoelectronic and/or photoelectrochemical device comprising a conductive support layer, n-type semiconductor, a sensitizer or light-absorber layer, a hole transporting layer, a spacer layer and a back contact, wherein the n-typ ...
Development of practical systems for photoelectrochem. conversion of solar energy to chem. fuel requires light absorbers that are efficient, durable, and scalable. Because no material currently meets all three requirements, intensive semiconductor discover ...
Semiconductor nanowires have demonstrated exciting properties for nanophotonics, sensors, energy technologies and end-of-roadmap and beyond-roadmap electronic devices. Fabrication schemes for nanowires are varied, but they fall into three general categorie ...
Multi-junction solar cells are known to have a considerably increased efficiency potential over their typical single junction counterparts. In order to produce low cost and lightweight multi-junction devices, the availability of suitable narrow (< 1.1 eV) ...
A method for manufacturing a semiconducting, organic, covalent polymer network thin film is disclosed, said method comprising the steps of deposing a solution comprising azide- containing monomers and electron-deficient alkyne-containing monomers onto a re ...
The present invention relates, for example, to a semiconductor structure containing multiple parallel channels in which several parallel conductive channels are formed within the semiconductor structure. Electric contact or electrostatic control over all t ...
The present invention relates to a Semiconductor device including a first electrode, a second electrode and at least one semiconductor material or layer between the first and second electrode. The semiconductor device further includes at least one field pl ...
