Defects in CdTe polycrystalline films grown by physical vapour deposition

Autor: Ernesto Diéguez, Edgardo Saucedo, Victoria Corregidor, L. Fornaro, J. L. Castaño

Publikováno v: Materials Science and Engineering: B. :525-528

CdTe films were grown by physical vapour deposition onto alumina, glass and silicon substrates. The best growth conditions were a source temperature in the range 700–830 °C, a substrate temperature from 450 to 550 °C and a growth time of about 4

Publikováno v: Crystal Research and Technology. 36:535-542

Semi-insulating CdTe single crystals doped with Ga were grown from the vapour phase by the modified Markov technique MMT. The study of the resistivity map in the cross-sections cut along the growth direction has been performed. The compensation pheno

Publikováno v: Optical Materials. 17:259-262

We report here results on buried-channel optical waveguides on GaAsP/GaAs material. These semiconductor devices were fabricated using chemical beam epitaxy (CBE). We discuss a method using epitaxial growth by selective area chemical beam epitaxy (SA-

TEA CO2-Laser Induced SF6+ Ba Beam-Surface Ionization

Autor: J. L. Castaño, V. Zapata, A. González Ureña, G. Makarov

Publikováno v: Journal of the Chinese Chemical Society. 42:393-398

A TEA CO2-laser induced SF6 + Ba beam-surface ionization process has been studied when vibrational excitation of SF6 molecules was carried out at (and near) the polished surface of the electrically heated up to 675 K polycristalline Ba. Electron emis

Publikováno v: Applied Physics Letters. 81:5153-5155

We report the possibility to grow semi-insulating (Cd,Zn)Te:Se crystals by the modified Markov method (MMM) from the vapor phase. When oriented Cd(Te,Se) seed material was used for the growth, lattice matching and doping with Se resulted in an increa

Publikováno v: Journal of The Electrochemical Society. 138:3039-3042

Direct writing laser doping from doped spun‐on glasses is reported. Under quasistationary regime, diffusion depths over 1 μm can be controlled across the laser power. Sheet resistances from below 20 up to 600 Ω/ for boron‐diffused samples and u
