Journal ArticleDOI
Modified compensation model of CdTe
Michael Fiederle,C. Eiche,M. Salk,R. Schwarz,Klaus-Werner Benz,W. Stadler,D. M. Hofmann,Bruno K. Meyer +7 more
TL;DR: In this paper, a new compensation model based on a deep intrinsic donor level is presented, which is used together with an appropriate segregation model to calculate axial distributions of resistivity which are compared with spatially resolved resistivity measurements.
Journal ArticleDOI
Comparison of CdTe, Cd0.9Zn0.1Te and CdTe0.9Se0.1 crystals: application for γ- and X-ray detectors
Michael Fiederle,D.G Ebling,C. Eiche,D.M. Hofmann,M. Salk,W. Stadler,Klaus-Werner Benz,Bruno K. Meyer +7 more
TL;DR: In this article, a common deep level close to the middle of the bandgap has been identified, responsible for the compensation effect in all three systems, and high resistivity and n-type conductivity were achieved in CdTeSe materials for the first time.
Journal ArticleDOI
Investigation of compensation defects in CdTe:Cl samples grown by different techniques
TL;DR: A detailed analysis of the photoinduced current transients of differently grown CdTe:Cl samples was performed in the 100-140 K range in order to investigate the influence of different growth techniques (sublimation, Bridgman method, and traveling heater method) on compensation defects as mentioned in this paper.
Journal ArticleDOI
Studies of the compensation mechanism in CdTe grown from the vapour phase
Michael Fiederle,D.G Ebling,C. Eiche,P. Hug,W. Joerger,M. Laasch,R. Schwarz,M. Salk,K.W. Benz +8 more
TL;DR: In this article, semi-insulating titanium and vanadium-doped cadmium telluride crystals were grown from the vapour phase and the results of the electrical characterisation obtained by Hall measurements, photoinduced current transient spectroscopy (PICTS), admittance spectrograms and time-of-flight measurements were shown.
Journal ArticleDOI
Radiation detector properties of CdTe0.9Se0.1:Cl crystals grown under microgravity in a rotating magnetic field
Michael Fiederle,C. Eiche,W. Joerger,M. Salk,Alexander S. Senchenkov,A. V. Egorov,D.G Ebling,K.W. Benz +7 more
TL;DR: In this paper, the influence of growth conditions on radiation detector performance was studied by examining Cd(Te,Se):Cl crystals during the PHOTON 8 mission, which were grown by the travelling heater method under microgravity conditions during the mission.
