Among the numerous magnetic semiconductors there is a family of ternary compounds MnX11Te4. For the first time the optical and electrical parameters of these materials as well as the methods of preparing of the diode structures were presented in works (AVERXJRVA et al. ; BEKIMRETOV e t al.). Investigations of the optical, electronic, photoelectric and luminescence properties of the ternary compounds MniIITe, with the magnetic
Thin (CuInSe 2 ) 1--x (2ZnSe) x (0.0 x 0.42) p-type films were synthesised on glass substrates by pulsed Nd : YAG laser deposition at 1064 nm with a repetition rate of 3 Â 10 --2 Hz and a pulse width of 1.1 ms. The applied laser energy was kept in the range 160-190 J per pulse. The target materials and films were characterised by X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX) and hot-point probe technique for electrical characterisation. The as-grown layers were single phase and polycrystalline. The films showed a phase transition from chalcopyrite to sphalerite in the region 0.3x 0.4. Photosensitive structure of In/p-(CuInSe 2 -2ZnSe) and n-InSe/p-(CuInSe 2 -2ZnSe) types were obtained. Spectral dependences of the photoconversion relative quantum efficiency in relation to the type of energy barrier and chemical composition of thin films were studied. Analyses of the results showed that the structures based on CuInSe 2 -2ZnSe films could be used as wide-band photodetectors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
