The dependence of the photoionization cross-section on photon energy is calculated for shallow donors in infinite-barrier GaAs/Ga(1-x)Al(x)As quantum well as a function of well width. The effect of a magnetic field is also considered.

PHOTOIONIZATION OF IMPURITIES IN QUANTUM-WELLS ELSAID, M; Tomak, Mehmet (1992-06-01) The dependence of photoionization cross-section on photon energy is calculated for shallow donors in quantum wells. The resulting spectra is completely different for light polarized along and perpendicular to the growth direction.
IMPURITY PHOTOIONIZATION IN SEMICONDUCTORS ILAIWI, KF; Tomak, Mehmet (1990-01-01) The dependence of photoionization cross-section on photon energy is calculated using different impurity potentials including the Hülthén potential. The effect of anisotropy is taken into account and is shown to affect the spectral dependence drastically.
PHOTOIONIZATION OF IMPURITIES IN HETEROJUNCTIONS ELKAWNI, MI; Tomak, Mehmet (1992-01-01) The spectral dependence of the photoionization cross-section is calculated for shallow donors in GaAs/GaAlAs heterojunctions. The resulting spectra is found to be different for light polarized along and perpendicular to the growth direction. The calculations are repeated for both infinite- and finite-barrier models.
Photovoltaic and photophysical properties of a novel bis-3-hexylthiophelle substituted quinoxaline derivative GÜNEŞ, Serap; Baran, Derya; Günbaş, Emrullah Görkem; Oezyurt, Funda; Fuchsbauer, Anita; Sariciftci, Niyazi Serdar; Toppare, Levent Kamil (Elsevier BV, 2008-09-01) We report on the photophysical properties and photovoltaic performance of a polythiophene derivative, poly-2,3-bis(4-tert-butylphenyl)-5,8-bis(4-hexylthiophen-2-yl)quinoxaline(PHTQ) as an electron donor in bulk heterojunction Solar Cells blended with the acceptor 1-(3-met hoxycarbonyl)propyl-1-phenyl-[6,6]-methanofullerence (PCBM). Devices were composed of PHTQ and varying amounts of PCBM (1:1, 1:2, 1:3, 1:4 w-w ratio). The components were spin cast from ortho-dichlorobenzene (ODCB) and characterized by mea...
Photovoltaic Effect and Space Charge Limited Current Analysis in TlGaTe2 Crystals QASRAWI, ATEF FAYEZ HASAN; Yaseen, T. R.; Eghbariy, B.; Hasanlı, Nızamı (Institute of Physics, Polish Academy of Sciences, 2012-07-01) Anisotropic space charge limited current density analysis and photovoltaic effect in TlGaTe2 single crystals has been investigated. It is shown that, above 330 K, the crystal exhibits intrinsic and extrinsic type of conductivity along (c-axis) and perpendicular (a-axis) to the crystal's axis, respectively. The current density (J) is found to be space charge limited. It is proportional to the square and three halves power of voltage (V) along the a- and c-axis, respectively. Along the a-axis and at sufficien...
