This Nanografi bismuth telluride (Bi2Te3) sputtering target is a 99.999% pure source for depositing thin films by sputtering. Each target measures 2'' across with a thickness of 0.125'', and it is supplied as a single piece.
Bismuth telluride is a compound of bismuth and tellurium and behaves as a semiconductor. Alloyed with antimony or selenium, it becomes an efficient thermoelectric material used for refrigeration and portable power generation. It is also a topological insulator, so its physical properties depend on thickness.
Bi2Te3-based alloys are the leading semiconductor materials for bulk thermoelectric devices operating near room temperature. Nanostructured thin films of these alloys are drawing strong research interest, as well-ordered film structures can deliver higher thermoelectric efficiency than bulk material. Sputtering gives a repeatable route to such films that can be scaled from small R&D work to production batches on medium to large substrates, while its many process parameters allow close control over film growth and microstructure.
- Sputter deposition of bismuth telluride thin films onto substrates such as silicon wafers.
- Research on thin film thermoelectric materials for chip-scale micro-coolers used in thermal management of high-powered micro/nano-electronics.
- Development of flexible micro-power generators for energy harvesting.
- Studies of how composition, microstructure, morphology, thickness and substrate conditions affect thermoelectric properties of thin films.
- Sputter etching where high etching anisotropy is required.
