“…Thin polycrystalline films of Sb 2 Se 3 semiconductors have been commonly used as absorbers to fabricate cost-effective solar cells and Hall effect devices25. Sb 2 Se 3 films are widely applied in optical materials, thermoelectric cooling, and power conversion devices because of their high thermoelectric power26. Over the past two decades, many methods have been developed to prepare Sb 2 Se 3 nanostructures (nanotubes, NWs, and nanobelts).…”

In this study, we measured the thermal conductivity and Seebeck coefficient of single Sb2Se3 nanowires and nanowire bundles with a high resistivity (σ ~ 4.37 × 10−4 S/m). Microdevices consisting of two adjacent suspended silicon nitride membranes were fabricated to measure the thermal transport properties of the nanowires in vacuum. Single Sb2Se3 nanowires with different diameters and nanowire bundles were carefully placed on the device to bridge the two membranes. The relationship of temperature difference on each heating/sensing suspension membranes with joule heating was accurately determined. A single Sb2Se3 nanowire with a diameter of ~ 680 nm was found to have a thermal conductivity (kNW) of 0.037 ± 0.002 W/m·K. The thermal conductivity of the nanowires is more than an order of magnitude lower than that of bulk materials (k ~ 0.36–1.9 W/m·K) and highly conductive (σ ~ 3 × 104 S/m) Sb2Se3 single nanowires (k ~ 1 W/m·K). The measured Seebeck coefficient with a positive value of ~ 661 μV/K is comparable to that of highly conductive Sb2Se3 single nanowires (~ 750 μV/K). The thermal transport between wires with different diameters and nanowire bundles was compared and discussed.

“…Different research groups [13][14][15][16][17] have prepared Cd 1−x Zn x Se thin films by different techniques and studied their structural, optical and electrical properties. We have prepared Cd 1−x Zn x Se films by the resistive thermal evaporation technique with various zinc contents incorporated along with cadmium such as x = 0.2, 0.4, 0.6 and 0.8.…”

Ellipsometric analysis of Cd_1−xZn_xSe thin films prepared by a thermal evaporation technique

Cd 1−x Zn x Se is an important semiconducting alloy because it is possible to tune its physical properties by controlling its composition x. Thin films of Cd 1−x Zn x Se with different compositions (x = 0.2, 0.4, 0.6 and 0.8) were deposited onto a glass substrate by the resistive thermal evaporation technique. Optical properties such as optical constants and band gap energy of these films were examined by using a spectroscopic ellipsometer. It was found that the optical constants (n and k) decrease with the addition of Zn content in the alloy. In comparison, the band gap energy was also determined by using transmission spectra and found to agree with that of the ellipsometric results. These analyses confirm that the band gap energy increases with the increase of Zn content in the alloy. The composition of the films was estimated by energy dispersive analysis of x-ray studies. The structural properties of these films were studied by using an x-ray diffractometer (XRD). The XRD patterns reveal that the two binary compounds have been completely transformed into a ternary compound with hexagonal (wurtzite) structure having preferred orientation along the c-direction with (002) planes.

“…The deposition technique and its associated parameters have a characteristic effect on nucleation and growth of the thin films. Different workers [7][8][9][10][11] have prepared Cd 1-x Zn x Se films by different techniques and their structural, optical and photo electrochemical properties have been studied. However, few efforts have not been made to study the structural, optical and electrical properties of the thin films of Cd 1-x Zn x Se prepared from the mechanical mixed of CdSe and ZnSe.…”

Thin films of Cd 1-x Zn x Se (x = 0, 0.2, 0.4, 0.6, 0.8 & 1) with variable composition have been deposited onto glass substrates using mechanically mixed CdSe and ZnSe by vacuum evaporation technique. These thin films have been characterized through the XRD, optical and electrical characterization technique. XRD patterns confirm the preferred orientation and polycrystalline nature of the thin films. Absorption edge shifts towards lower wavelength range with the increase of Zn concentration. The variations of energy band gap have been determined and discussed with Zn concentration. The electrical conductivity of so prepared thin films has been determined in the temperature range from room to 413 K. The result indicates that the electrical conductivity decreases with increasing Zn content
