Chalcogenide Photovoltaics: Physics, Technologies, and Thin Film Devices

This primary accomplished description of an important fabric homes and equipment points closes the space among common books on sun cells and magazine articles on chalcogenide-based photovoltaics. Written by means of very well known authors with years of functional adventure within the box, the e-book covers II-VI and I-III-VI2 fabrics in addition to strength conversion at heterojunctions.

Example text

The analysis of the lattice parameters of CeGa 2 at room temperature is in agreement with a tri valent state for Ce in this compound. 5 K on a polycrystalline sample, indicate that CeGa 2 exhibits an almost ferromagnetic behaviour. Although the initial susceptibility is high, a metamagnetic transition is observed around 200 Oe. The thermal variation of the magnetization, measured in low field, presents a maximum around 4 K with an inflexion point at about 9 K. However, it is difficult to conclude from these measurements for a ferro- or an antiferromagnetic behaviour and to locate the ordering temperature.

From the magnetic neutron-scattering cross section one can calculate the static magnetic susceptibility XQ(T) via a sum rule [7]. In cubic symmetry it reads f dES(Q,E)/f(E) J—oo = (ye2/meC2)2F(Q)2 e" 2 W χ0(Τ)/(2μ2Β). (3) Before applying eq. (3) to S(Q, E) as defined by eq. (2), this latter quantity must be extended properly to hold for E < 0, too. , the contribution linked to d ) . 001) emu/mol as measured for our sample in a Faraday magnetometer. , at low temperatures it is greatly reduced compared to its free-ion CEF value.

B. 3640, D-7500 Karlsruhe, Fed. Rep. Germany We present absolute intensities for inelastic magnetic neutron-scattering from cubic CePb3. Both quasi-elastic scattering and inelastic scattering due to CEF excitations are observed and analyzed in terms of a free-ion CEF scheme. We conclude that in CePb3, a Γ7 doublet is the 4f ground-state.
