A crystallographic study using a four-circle diffractometer was carried out on a twin system observed in chalcopyrite-type AgGaS2 crystals grown by the Bridgman technique. The twin components have (112) planes in common, and coincide with each other in the direction of the atomic arrangement. The twin system is essentially a glide-twin characterized by successive glides of atomic layers paralle...

AgGaS2 single crystals were grown by modified Bridgman method. The present work is devoted to investigate the electrical and thermoelectric transport properties of AgGaS2. Measurements of electrical conductivity and Hall effect were performed in the temperature range (380-660 K) and (344-690 K) for thermoelectric power. Our investigation showed that our samples are P-type conducting . The forbi...

A new family of quaternary diamond-like semiconductors (DLSs), Li2HgMS4 (M = Si, Ge, Sn), were successfully discovered for the first time. All of them are isostructural and crystallize in the polar space group (Pmn21). Seen from their structures, they exhibit a three-dimensional (3D) framework structure that is composed of countless 2D honeycomb layers stacked along the c axis. An interesting f...

AgGaS2 (AGS) nanocrystals that exist in the orthorhombic phase were successfully prepared for the first time through a one-pot colloidal synthetic strategy using suitable coordinating solvents. These orthorhombic AGS nanocrystals were found to display great potential in visible-light-driven photocatalysis.
