Photoelectric conversion device (1) comprising semiconductor electrode (15) having semiconductor layer (7) carrying a sensitizing dye, counter electrode (9) arranged opposite to the semiconductor electrode (15) and electrolyte layer (13) arranged between t ...
Microcavity comprising two reflectors, at least one semiconductor layer separating said reflectors and a semiconductor quantum well wherein at least one of said reflectors and of said at least one semiconductor layer comprises a structure which is adjusted ...
The charging kinetics of viologen-TiO2 displays was studied by electrochem. techniques. Resistive and capacitive effects were analyzed in terms of a simple model for the charging kinetics in optical switches. For large-segment devices the model resistance ...
In this work we report on solar blind (Al,Ga)N photovoltaic metal-semiconductor-metal (MSM) detectors with a cutoff wavelength as short as similar to270 nm. (Al,Ga)N heterostructures, that allow backside illumination, were grown on sapphire substrates by b ...
An electrically pumped VCSEL (10) and a method of its fabrication are presented. The VCSEL (10) comprises an active cavity material (14) sandwiched between top and bottom DBR stacks (12a, 12b), the top DBR (12b) having at least one n-semiconductor layer. T ...
Transparent nanostructured NiO electrodes were prepd. by heating Ni(OH)2 sol-gel films at 300-320°. Nanostructured NiO (bunsenite) behaves as a p-type semiconductor and has an indirect band gap of 3.55 eV. It shows a strong anodic electrochromic effect, as ...
Single crystals of layered semiconductors such as WS2 and MoS2 have already proven their efficiency as active elements in photovoltaic cells. Due to their high optical absorption coefficient in the visible range, these materials could be used in the form o ...
The present paper describes a new method for manufg. a nanostructured porous layer of a semiconductor material on a conducting plastic substrate for use in an electrochem. or photoelectrochem. cell. The method involves the deposition of a layer of semicond ...
'Elec.-paint displays' are electrochromic displays with dyed nanostructured metal-oxide electrodes, e.g. viologen-derivatized nanostructured titanium dioxide electrodes. Such displays are particularly promising for applications with low switch frequency, l ...
An entire microsystem for high accuracy magnetic field measurement based on vertical Hall devices has been simulated. In accordance with existing knowledge about semiconductor physics and experimental results, a functional SPICE- model for a vertical Hall ...
