	Preparation and properties of pyroelectric detectors for optoelectronic applications (II) Novotný, Jan ; Zelinka, Jiří ; Podvalová, Zdislava ; Malina, Václav ; Vávra, Vladimír ; Krechler, Jindřich ; Franc, V. ; Fronc, Václav Technology of preparation of doped single crystals of triglycine sulphate for application in optoelectronics is described. Internal report contains also technology of preparation of simple pyroelectric detectors which operate in infrared region, wavelengths 2-25ćm. Measurement methods for infrared detectors and their basic technical parameters are presented. The prepared infrared detectors operate as non-cooling elements with hybrid high impedance amplifier. Detailed record
	Characterisation of InP layers prepared by the LPE method with Pr and Nd addition in the growth melt Grym, Jan ; Procházková, Olga ; Zavadil, Jiří ; Žďánský, Karel High purity InP epitaxial layers were grown by LPE from the melt conataining, besides essential components, also rare-earth elements admixture. The layers were examined by SEM, low temperature PL spectroscopy, C-V measurements and temperature dependent Hall effect. The behaviour and the impact of Pr and Nd were compared. The concentration of shallow impurities was reduced by up to three orders of magnitude. PL spectra were markedly narrowed and fine spectral features were resolved. Detailed record
	Preparation and properties of pyroelectric detectors for optoelectronic applications (I) Novotný, Jan ; Březina, Bohumil ; Zelinka, Jiří ; Malina, Václav ; Vávra, Vladimír ; Zavadil, Jiří ; Velvarský, Jaroslav ; Fronc, Václav ; Pospíšil, Miroslav The photodetectors operating in the 0.8-20ćm wavelength region have been prepared. The report is devoted to the research and realisation of novel types of materials on the basis TGS single crystals family. The prepared detectors have been tested in static and dynamical regime of operation. The obtained results have been passed on TESLA BLATNÁ Company. Detailed record
