Synthesis and temperature-tuned band gap characteristics of magnetron sputtered ZnTe thin films

An investigation on structural and optical properties of nanocolumnar ZnTe thin films grown by glancing angle technique

“…The direct bandgap energy values are close to the reported values for ZnTe thin films [48][49][50] . Based on the transmission spectra, the refractive index (n) has been calculated using the Swanepoel method, because it is a determinative factor in the efficiency of an antireflection coating [6,20]. 2 20 .…”

“…Over the past decades, II-VI compounds have considerably been applied in different fields because of their exotic properties [1], among which ZnTe material, is of important applications due to its direct band gap of 1.7-2.6 eV [2]. For instance, its application in photovoltaics and photo-electrochemical solar cells has enormously attracted the attention of many types of research [3][4][5][6].…”

“…As a result, it has been found applicable in optoelectronic and microelectronic devices such as detectors [10], thin film transistors [2], x-ray imaging system [10,11], etc. Several methods have been proposed and applied in the deposition of ZnTe thin films: RF Sputtering [12], electrodeposition [3,13], thermal evaporation [2,14], molecular beam epitaxy (MBE) [15,16], electron beam evaporation [6], pulsed laser deposition (PLD) [4,17], hot-wall evaporation [18]. Among them, physical vapor deposition is found to be more applicable for ZnTe and other II-VI compounds [19][20][21][22][23][24][25][26].…”

Thickness Effect on Some Physical Properties of RF Sputtered ZnTe Thin Films for Potential Photovoltaic Applications

“…[ 1 , 2 , 3 , 4 ], thin layers of zinc telluride (ZnTe) are used in various modern technologies, which are implemented in various micro- and nano-structured devices, such as light emitting diodes, solar cells, photodetectors, etc. [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. Although it is a popular material, there are few publications and studies regarding its material engineering.…”

“…For the deposition of thin layers [ 16 , 17 , 18 , 19 , 20 ], more physical and chemical growth paths are known, such as molecular beam epitaxy (MBE) [ 21 ], chemical bath deposition (CBD), electron-beam evaporation, thermal evaporation, magnetron sputtering [ 12 ], and electrodeposition [ 19 , 20 , 21 , 22 ]. The ZnTe thin layer properties depend directly on the deposition method, deposition conditions, and the growth direction imposed by the substrate when the substrate is crystalline [ 5 , 6 , 7 , 8 , 23 ]. Some studies have established the ideal deposition conditions for various deposition methods, to obtain ZnTe layers with the necessary physical properties, a well-defined morphology, and crystal structure, but there is no systematic reproducible technology available for high performance ZnTe coating fabrications [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 24 , 25 ].…”
