Surface acoustic waves (SAW) are an ideal tool for the noninvasive detection of conductivity and carrier distributions in otherwise unstructured semiconductor systems. Here we demonstrate a technique that allows for spatially resolved experiments wit

Eight gas chromatograms present an unusual composition of alkanes ( including branched alkanes) from cuticular waxes. In plants of a lower phylogenetic class (liverwort, lichens), further in seeds and sprouts of tubers (Solanaceae) and especially in

We demonstrate room-temperature acoustic charge transport of electrons and holes in an InGaAs/GaAs heterostructure. The carriers are optically generated by interband absorption and then separated, stored, and transported in the piezoelectric potentia

A new method to optically examine surface acoustic wave (SAW) propagation on a semiconductor chip is presented. This visualization method is based on the influence of a SAW on the optical properties of a piezoelectric semiconductor. There are two int

Sophisticated high frequency signal processing as well as sensor applications based on surface acoustic waves (SAW) often require a complex transducer layout. We present a simple numerical technique based on a Huygens-type construction to calculate a

Surface acoustic waves (SAWs) are excited on the GaAs (001) surface by using interdigital transducers, designed for frequencies of up to 900 MHz. The emitted phonons with wavelengths down to 3.5 μm are visualized and characterized by combined x-ray
