Investigation of indium-defect pairs in CdTe by PAC spectroscopy
Abstract PAC spectroscopy is used to investigate indium-defect pairs in p-CdTe. It is shown that the frequently reported EFG 60 ( ν Q =60 MHz, η =0.15) is not the only signal which characterizes In-AExpand

Hafnium, cadmium and indium impurities in 4H-SiC observed by perturbed angular correlation spectroscopy
Abstract The annealing behaviour of hafnium impurities in silicon carbide after ion implantation and the formation and stability of complexes of hafnium in 4H-SiC were studied by perturbed angularExpand

Iron-containing defect-rich mixed metal oxides for Friedel–Crafts alkylation
Abstract Several stable iron-containing spinel oxides with the composition CuFe 2 O 4 or FeCr 2 O 4 were prepared by different methods including thermal nitrate decomposition, combustion synthesis,Expand

Band-gap level of the cadmium vacancy in CdTe
The reaction Ag Cd → Ag i + V Cd was used to create cadmium vacancies V Cd in the space charge region of a Schottky contact on p-type CdTe. At T = 380 K, the Ag i + ions were drifted out of the spaceExpand

Hydrogen passivation of cd acceptors in III–V semiconductors studied by PAC spectroscopy
Abstract Formation, structure, and stability of hydrogen correlated complexes, created at Cd acceptors in GaP, InP, and InAs have been studied after plasma charging as well as after H+ and/or He+Expand

Complex formation in In- and Ag/Cu-doped CdTe
Abstract Interactions between In donors and Ag, Cu and acceptor-like native defects have been studied in p- and n-type CdTe single crystals by perturbed angular correlation (PAC) spectroscopy onExpand

Radiotracer Spectroscopy on Group II Acceptors in GaN
One Be-related donor level in the band gap of GaN was identified by Radiotracer Deep Level Transient Spectroscopy (DLTS) and Thermal Admittance Spectroscopy (TAS). The radioactive isotope Be wasExpand

Acceptor-Hydrogen Complexes in InAs
Complex formation at indium donors in p-CdTe
After diffusion of silver into p-CdTe at room temperature, two electric field gradients (EFG) are observed at 111 In/ 111 Cd probe atoms at T = 77 K: v Q1 = 61 MHz, η 1 = 0.15 and v Q2 = 30 MHz, η 2Expand
