Bismuth selenide doped with cobalt sputtering targets

Bismuth selenide (Bi₂Se₃) doped with cobalt (Co) is used in various advanced materials applications due to its unique properties.

Sputtering Targets:

Purpose: In thin-film deposition, sputtering targets made of Bi₂Se₃ doped with Co are used to create thin films of the material on substrates. The doping introduces changes in the electronic and magnetic properties of the films.

Applications: These films can be used in a range of electronic and optoelectronic devices, including sensors, detectors, and components in quantum computing.

Topological Insulators:

Topological Insulator Properties: Bi₂Se₃ is a well-known topological insulator, which means it has insulating bulk properties but supports conductive surface states. Doping with Co can modify these properties.

Applications: These doped materials are explored for their potential in spintronic devices, which leverage both the charge and spin of electrons. They are also of interest for research into quantum computing and other advanced technologies.

Thermoelectric Materials:

Thermoelectric Properties: The doping of Bi₂Se₃ with cobalt can alter its thermoelectric properties, which are important for converting temperature differences into electrical voltage.

Applications: Improved thermoelectric materials can be used in energy harvesting and cooling applications.

Magnetic Properties:

Magnetic Doping: Adding cobalt to Bi₂Se₃ introduces magnetic elements, which can result in magnetically doped topological insulators. This combination can lead to interesting phenomena such as magnetic topological states or quantum anomalous Hall effects.

Applications: These materials are studied for their potential in creating novel electronic devices that utilize both magnetic and topological properties.

Optoelectronics:

Optoelectronic Devices: The unique electronic properties of Co-doped Bi₂Se₃ films make them suitable for various optoelectronic applications, including photodetectors and light-emitting devices.

When using Bi₂Se₃ doped with cobalt as a sputtering target, the composition and doping levels are carefully controlled to achieve the desired properties in the deposited films. This material can be valuable for research and development in cutting-edge technologies and applications.
