A Contribution of Carrier Transport Processes to the Photoacoustic Effects in Doped Narrow Gap Semiconductors
(American Institute of Physics, 2003)
The contribution of free carrier transport processes to the photoacoustic effect in doped AIVBVI compounds was investigated using the photoacoustic (PA) frequency modulated transmission technique as a valuable tool in the ...
Thermoelastic and Electronic Deformation Components of Photoacoustic Signal in Two-layer System
(The Japan Society for Analytical Chemistry, 2001)
A model was derived in order to study the dependence of the photoacoustic signal on the thermal, elastic and carrier
transport properties of two-layer samples. The various systems were considered: the conductor-semiconductor, ...
Zlato u kvarcno-hematitskim mineralizacijama okoline Aldinca na Staroj planini / Gold in quartz-hematitic mineralisations of the Aldinac area at Stara planina Mountain
(Geoinstitut, 2004)
Rudnu zonu Aldinca pretežno izgrađuju gabroidne stene, predstavljene piroksenskim gabrovima i dijabazima, u koje su utisnute granitoidne stene, pretežno granodiorit-porfiriti, a u manjoj meri, kvarc-latiti i daciti. ...
X-ray investigations of scheelite and pyrite from Aldinac (Stara Planina Mt.)
(Geoinstitut, 2003)
At one representative sample there was indiced powder diffraction pattern and done qualitative-semiquantitative X-ray powder diffraction analysis. It was established that the investigated sample contains scheelite and ...
Occurence of alunite and natroalunite at Veliki Bukovik (Raška, Serbia)
(Минно-геоложки университет “Св. Иван Рилски”, 2004)
Alunite and natroalunite from Veliki Bukovik near Raska (Serbia) were determined. There were obtained following unit cell dimensions and crystallochemical formulas:
