Allgemeine Beschreibung

Bismuth(III) telluride (Bi2Te3) is a thermoelectric material, which acts as a topological insulator: a quantum material with an insulating bulky gap and gapless edge. It forms thin films by different techniques, which include chemical method, electrodeposition and molecular jet method.
The binary chalcogenide, bismuth(III) telluride occurs as mineral tellurobismuthite in nature. 1-2

Materials for Advanced Thermoelectrics

Thermoelectric materials comprise a wide range of solid compounds distinguished by their ability to convert thermal and electrical energy.

2D Materials Matter: A Perspective on Biosensing Applications

Professor Ebrahimi and Professor Robinson (Pennsylvania State University, USA) summarize recent advances in the synthesis of these 2D materials, resulting material properties, and related applications in biosensing of neurotransmitters, metabolites, proteins, nucleic acids, bacterial cells, and heavy metals.

Silicides: Promising Thermoelectric Materials

The price of tellurium, a key component in many thermoelectric materials, has risen in recent years, leading to the search for more cost-effective substitutes. This article presents silicide materials as a cheaper potential alternative.
