We studied the dependence of porous silicon (PS) morphology on fabrication conditions and the link between morphology, porosity and optical properties. P-type (100) silicon wafers with resistivity of 10Ωcm were electrochemically etched in a HF:ethanol:water mixture at various HF concentrations and current densities. Porosity and thickness of the samples were determined gravimetrically. Detailed information...
A low drift nanomanipulation device operating in a scanning electron microscope was constructed. The device allowed to manipulate and to characterize the electrical properties of flexible and highly conductive gold nanowires with diameters down to 15nm. Individual nanowires could be electrically contacted either to substrate electrodes or to movable tip electrodes of the nanomanipulation device. Measuring...
