“…Chalcogenides and pnictides based ternary tetrahedral (A II B IV C 2 V and A I B III C 2 VI ) semiconductors, which build a broader class of semiconducting materials with varied structural, mechanical, electrical, and optical properties and have attracted interest because of their growing scientific and technological applications. Among complex solids, ternary compounds are semiconductors having a large energy direct band gap, strong non linearity, low thermal conductivity, broad transparency window, lower melting temperatures, and a tetragonal chalcopyrite crystal structure [1][2][3][4][5][6]. Once studied for their low thermal conductivities, currently they are investigated for applications like as electromagnetic (EM) screening, spintronics [7][8], and photovoltaics [9].…”

A study of experimental data reveals that the bulk modulus of chalcogenides and pnictides based chalcopyrites (AIIBIVC2 V and AI BIIIC2 VI) can be explained by a simple scaling rule that rely only on the crystal ionicity, ionic charge product, and the melting temperature. PVV theory of crystal ionicity, temperature dependence of elasticity and product of ionic charge theory are taken into account for the study. Based on this result, a simple microhardnessbulk modulus relation is applied to evaluate the microhardness of the complex compounds; which correspond well with the experimental data and other published results. The proposed findings support in the modeling of emerging semiconductor materials and even understanding of their mechanical properties for optoelectronics, photovoltaic, electromagnetic (EM) screening, and spintronic applications.

“…In the lower wavelength region, higher quantum e ciency is found for lower thickness of buffer layer. As quantum e ciency is a measure, how effectively charge carriers are being separated near the depletion region (Singh et al 2016); less recombination is found for lower thickness of buffer layer leading to higher quantum e ciency.…”

The use of ZnTe as the buffer layer in the Cu 2 ZnSnS 4 (CZTS) based solar cells showed the improvement in overall e ciency. It may also reduce the overall cost of these cells as both the layers (absorbing and buffer) are having eco-friendly and earth abundant constitutes. The sol-gel spin coating method is used for the deposition of CZTS thin lms on the corning glass substrates. The X-ray diffraction studies showed the peaks corresponding to (112), ( 200), ( 220) and ( 312) planes which con rmed the formation of essential kesterite phase. The optical band gap of the deposited lms was found around 1.9 eV by UVvisible spectrophotometer. The optimum thickness of the absorber layer was investigated based on the performance of ZnO:Al/ZnO/ZnTe/CZTS/Mo cell structure by using AMPS-1D simulation tool, while the tool was moulded by the investigated data from the sol-gel deposited CZTS thin lms. The e ciency of solar cell was found to be increased till 22.64% with increment in the thickness of absorber buffer layer up to 2500 nm and beyond this it starts to decrease. In addition to this, it was also analysed that the current density is improved with operating temperature as it is one of the requirements in the high solar radiation areas where the temperature rise more than 50 C in summer.

“…The demand for the unique properties of nanomaterials leads to the expansion of methods for their preparation, in particular, to the search for commercially available starting reagents, reducing environmental damage, and optimizing the yield of the product without loss of their properties [1,2]. The chalcogenide quantum dots (QDs) are the most widely used in the fabrication of light-emitting diodes [3,4], radiation detectors [5,6], solar cells [7,8], as biological labels [9,10], etc.…”

One of the most effective strategies for reducing the surface defects in nanocrystals is the shell growth on the already formed cores. This approach provides not only an increase in the photoluminescence quantum yield (PL QY) but also prevents the diffusion of cations and anions from the core material. Gram scale synthesis of the green-emitting core ( 10g) was performed by interaction of highly reactive substituted selenourea ((Z)-N-(octadec-9-enyl)morpholine-4-carboselenoamide) with the cadmium and zinc linoleates mixture at 240 °C. Verification of the shell growth method based on the volume ratios of the core and the core with a shell led to the creation of a series of core/shell/shell Cd0.1Zn0.9Se/CdxZn1-xS/ZnS (x = 0.1; 0.25; 0.4; 0.6; 0.75) quantum dots (QDs). Deposition of the first shell ((Z)-1-(octadec-9-enyl)-3phenylthiourea) of CdxZn1-xS composition with a thickness of 2 monolayers (MLs) (epitaxial growth) resulted in blue (x = 0.1 and 0.25) and red (x = 0.4; 0.6 and 0.75) shifts in emission bands and an increase in PL QY (up to 71 %). The deposition of the second ZnS shell (2 MLs), the same for all compositions, was not epitaxial to the core, which brought a change in shape but did not affect the optical properties of the material. The analysis of Cd0.1Zn0.9Se/CdxZn1-xS/ZnS core/shell/shell by EDS, XPS, and XRD methods, confirmed the accordance of the initial ratios with the given compositions and sizes.
