	STUDY OF ELECTROPHORETIC DEPOSITION OF Pd METAL NANOPARTICLES ON InP AND GaN CRYSTAL SEMICONDUCTORS FOR H2 GAS SENSORS Žďánský, Karel ; Yatskiv, Roman ; Grym, Jan ; Černohorský, O. ; Zavadil, Jiří ; Kostka, František Deposition of Pd nanoparticles (NPs) on InP or GaN single crystal wafer was performed from isooctane colloid solution. Diodes were prepared by making Schottky contact with colloidal graphite on Pd NPs partly coated surface and ohmic contact on the blank side of the wafer. It was found that several ppb of hydrogen in nitrogen gas can be detected by monitoring the change of diode current at a constant bias voltage. Diodes made on GaN were about ten times more sensitive to hydrogen than those made on InP. Detailed record
	Control system of the laser topographer Kostka, František ; Žďánský, Karel ; Zavadil, Jiří ; Starý, Robert Universal apparatus for measuring photoluminescence over surface of semiconductor samples was designed and realized. Detailed record
	Control system of the Heat Flux furnace Kostka, František ; Zelinka, Jiří ; Kostka, Petr ; Houška, Zdeněk ; Zavadil, Jiří ; Starý, Robert ; Krechler, Jindřich ; Žďánský, Karel A control system for a two-crucible furnace for DTA has been designed and realized. Samples of heavy metal oxide glasses have been analysed by the system. Detailed record
	Films of Metal Nanoparticles Deposited on Semiconductors by Electrophoresis: Technology and Characterization Žďánský, Karel ; Zavadil, Jiří ; Kacerovský, Pavel ; Kostka, František ; Lorinčík, Jan ; Černohorský, O. ; Fojtík, A. ; Müller, M. ; Kostejn, M. Layers of nanoparticles in micelle enclosures were deposited on InP substrates by electrophoresis from isooctane colloid solutions containing Pd or Ag nanoparticles. The layers were investigated by SIMS, low-temperature photoluminescence spectroscopy and topography, absorption spectroscopy, Raman spectroscopy and sensitivity to hydrogen. Photoluminescence of InP was enhanced by the layers of Pd or Ag nanoparticles. Schottky barriers made on the n-type InP with layers containing Pd nanoparticles showed significant sensitivity to hydrogen in contrast to those containing Ag nanoparticles. Detailed record
	Control system for the furmance Heat Flux is described Kostka, František ; Zavadil, Jiří ; Zelinka, Jiří ; Starý, Robert ; Houška, Zdeněk ; Krechler, Jindřich The control system for the furnace Heat Flux is used for the temperature control of two volumes furnace and for the measuring of temperature difference between this two volumes Detailed record
	Autofluorescenční spektroskopie plicní tkáně Votruba, J. ; Zavadil, Jiří ; Javorský, Stanislav ; Kostka, František ; Klimtová, E. ; Brůha, T. In-vivo investigation of bronchial tissue by autofluorescence (AF) spectroscopy is reported. The study demonstrates differences of both the spectral shape and of signal intensity in photoluminescence spectra emitted from tissue affected by carcinoma as compared to healthy bronchial mucosa. It turns out that point measurements of AF spectra significantly increase the diagnostic utility of the AF method in discrimination of malignant and benign tissue as compared to commercial AF imaging systems. Detailed record
	Control system for laser topograph Kostka, František ; Žďánský, Karel ; Starý, Robert ; Šmíd, A. ; Krechler, Jindřich The goal of the laser-topograph control systems is the measured sample positions control in the perpendicular plane to the direction of the laser beam and data sampling from lock-in-amplifier. The lock-in-amplifier is detecting the secondary luminescence light from the measured sample. Detailed record
	Control system for fluorescence optical laboratory in the Institute of Radioengineering and Electronics Kostka, František ; Starý, Robert ; Krechler, Jindřich The goal of control system of the optical laboratory for luminescence is designed for controlling of all optical electronical and mechanical components of luminescence spectrometer like cryostat, laser, monochromator and data sampling from this physical experiment. Detailed record
	Mikropočítačový řídící systém pro výrobu optických tyčí a trubic Kostka, František A control system for the production of optical tubes and rods was developed in the IREE AS CR, as a continuation of prior effort to control drawing process of optical fibres. The latter system was modified; in particular in the power driving unit a newly constructed pulling device was added, enabling, with the help of an array of pulleys and a town belt, the drawing of optical tubes and rods. Detailed record
	Control system for optical deflector Silva, J. ; Kostka, František ; Krechler, Jindřich The PC control unit for the movement of the plan-parallel optical plate for the exposition of the large optic gratings. Detailed record
