متن کاملEmission of terahertz-frequency electromagnetic radiation from bulk GaxIn1−xAs crystals
We report an experimental study of femtosecond optically excited emission of terahertz frequency electromagnetic radiation from GaxIn1−xAs bulk crystals with alloy composition in the range between 0 x 0.65. The terahertz-emission mechanisms in bulk GaxIn1−xAs were studied as a function of carrier mobility, carrier concentrations, band gap as well as polycrystal grain size. Our experiments and a...
متن کاملTheoretical and experimental studies on the binding-energy of the shallow Zn acceptor in GaxIn1−xAs/InP quantum wells
In this work we study the behaviour of the shallow Zn acceptor in GaxIn1−xAs Quantum Wells (1.5 nm < Lz < 5 nm) lattice matched to InP. The experimental results as obtained by photoluminescence and optically detected impact ionisation to determine the binding energy of Zn are compared with a theoretical calculation. The binding energy increases from the 3D bulk value for smaller Lz, passes thro...
متن کاملThe Solid Solution
The monoclinic silicates Lu2SiO5 and Sc2SiO5 (Y2SiO5 type, space groupC2/c) form a solid solution Lu2−xScxSiO5. Samples with x = 0.5, 0.8, 1.0 were synthesized ceramically from Lu2O3, Sc2O3, and SiO2. The structures of three crystals with x = 0.88, 0.77, and 0.50 were refined on the basis of single-crystal X-ray diffraction data. The rare earth (RE) atoms occupy two crystallographically differe...
متن کاملSilver solid solution piezoelectrics
Using density functional theory calculations, we investigate the feasibility of using silver on the perovskite A-site in high-performance lead-free piezoelectrics. The calculations show that silver atoms are ferroelectrically active and can off-center by 0.5 Å. To induce Ag ferroelctric behavior absent in pure AgNbO3 we explore solid solutions of AgNbO3 with well-known simple perovskites PbTiO3...
