Backilluminated GaN/AlGaN heterojunction ultraviolet photodetector with high internal gain
We report on a backilluminated GaN/Al0.18Ga0.82N heterojunction ultraviolet (UV) photodetector with high internal gain based on metal-semiconductor-metal structures. A narrow band pass spectral respon...

Nondestructive identification of impurities in granular medium
We found differing characteristics in the backscattered signal depending on the presence of light and heavy impurities in a granular chain. The difference is due to soliton confinement in the region o...

We present recordings of currents mediated by single ion channel proteins obtained using planar, microstructured glass chips. In these chips, pores with diameters of 1–2 µm are produced by ion track etching and are used for patch clamping instead of using the classical micropipette. Our results represent success in using such devices to record from single channels in cell membranes. The planar chip greatly enhances the accessibility of the ion channel containing membrane and can serve as a workbench for experiments on single ion channels using combinations of patch clamp current recording with other single molecule techniques. ©2002 American Institute of Physics.
