The alloy composition that performed best consisted of approximately 50 percent cadmium, 25 percent tellurium and 25 percent selenium. To make their determination, researchers used a combination of ...

With global energy-related carbon dioxide emissions reaching an all-time high in 2021, the need for clean energy is more pressing than ever. One such alternative to fossil fuels is solar energy. Solar ...

Successful development of high-performance amorphous P-type oxide semiconductor using tellurium-selenium composite oxide. Professor Yong-Young Noh from the Department of Chemical Engineering at Pohang ...

Superior output and transmission properties are demonstrated in tellurium oxide-based amorphous p-type thin-film transistors (Se:Te = 1:4) processed with an optimal selenium alloying ratio. The ...

Crystalline studies of cadmium telluride solar cells have established how selenium makes them better. Adding the optimum amount of selenium in the right places could help increase efficiency from the ...

(Nanowerk Spotlight) Over the past decade, monoelemental tellurium (Te) has attracted great interest among researchers due to its intriguing properties of excellent photoresponse, fast ...

Russell Boyd ponders on how selenium — despite close similarities with its neighbours of the chalcogen family, sulfur and tellurium — continues to reveal chemical and biological activities of its own.

- a brittle silver-white metalloid element that is related to selenium and sulfur; it is used in alloys and as a semiconductor; occurs mainly as tellurides in ores of copper and nickel and silver and ...
