Due to the high solar radiation, constant over the whole year, solar energy is one of the most promising energy sources of the Caribbean for the next decades. But up to now this potential is not used, mainly due to the high costs of solar cells. Sola

Cu(In,Ga)Se 2 absorbers were investigated by surface photovoltage (SPV) in the Kelvin probe and fixed capacitor arrangements before and after deposition of CdS or In 2 S 3 buffer layers as well as before and after deposition of ZnO window layers. Eff

Single layers and combined layer systems with Cu(In,Ga)(S,Se)2, ZnS-nanodot (nd) and In2S3 layers were investigated by surface photovoltage spectroscopy in the Kelvin-probe arrangement and compared with the open-circuit voltage (VOC) of solar cells.

The adsorption of large organic molecules, including tetracene and perylene, on clean Si(100) is followed by scanning tunnelling microscopy (STM) in an ultra high vacuum environment. Different adsorption sites have been observed for these organic mol

The room temperature deposition of PTCDA on hydrogen passivated Si(1 1 1), as a function of evaporation temperature and dosing time, has been studied by STM. At low evaporation temperature, 200 °C, clusters with an average size of 3.5 nm are formed

Scanning tunnelling microscopy (STM) has been used to follow the adsorption of tetracene molecules on the Si(100)-2 × 1 surface. Two distinct types of adsorption are indicated by filled state images but three types may be distinguished in empty stat

The surface recombination velocity at clean and modified Si(1 0 0)2×1, Si(1 1 1)-1×1 and Si(1 1 1)-7×7 surfaces was studied with the pulsed photoluminescence technique. High resolution electron energy loss spectroscopy and low energy electron diff
Tuning in on single molecular states: adsorption sites and STM images of maleic anhydride on Si(100)

We show that, counterintuitively, maleic anhydride on Si(1 0 0) surfaces adsorbs on inter-row sites. Our first principles simulations establish that this site is preferred for coverages of less than 1/8 ML. In simulations of scanning tunnelling image
