The limitations of the performance of thermal resistors due to the electronic noises are investigated. Two applications of the thermistors are considered: the thermometer and the bolometer. The speed of the response of the probe is kept in mind in th

Electron irradiation at room temperature introduces in GaAs a donor type electronic state Tx at 0.18 eV, which is associated with the E3 electron trap. The presence of Tx is observed at depths d > 1.5 microm, which correspond to the limits of the dep

Drift mobility and electron concentration values in GaAs MESFETs obtained by capacitance-conductance measurements are corrected by means of a self-consistent iterative procedure. The final results are compared with the experimental Hall mobility data

The history of the metamaterial concept is outlined. The story started with the Institution of Veselago and continued almost thirty years later with the works of Pendry and co-workers. Their constructions resulting negative relative dielectric consta

A mobile phone can emit a few watts of power in the vicinity of the human head. The paper reviews the different types of mobile phones, the related exposures, the assumed biological effects as well as the health safety recommendations and test method

The thermal degradation of Al/Al/sub 0.20/Ga/sub 0.80/As Schottky junctions was studied up to 750/spl deg/C, by steps of 50/spl deg/C for 2 hours in forming gas. Current-voltage and capacitance-voltage measurements indicated, that the strong degradat

The explosion-like spread of mobile telecommunication raises the problem of the exposure of the user to the electromagnetic field. The most realistic experimental investigations of the exposure can be made in phantoms. An E-Field probe has been devel

The effect of the interface roughness and morphology (flat, dendrite-like and quasi-grating) on the electrical behaviour of Au/n-GaAs Schottky diodes were studied by current-voltage measurements. The results suggested that diodes with a dendrite-like

The basic problems and advantages related to spectrometric applications of GaAs-based radiation detectors for the X- and /spl gamma/-ray region are discussed. Two types of detectors are tested, based on (i) semi-insulating GaAs bulk substrate and (ii
