Thermoelectric devices: Used to fabricate critical thin film layers in high-performance thermoelectric modules, directly converting waste heat into usable electrical energy.
Photovoltaic Absorber Layer: Serves as an alternative absorber material for novel thin-film solar cells, exhibiting unique photoelectric response characteristics.
Phase Change Memory Material: Utilized in advanced phase change memory (PCM) devices, leveraging its rapid and stable crystalline-amorphous transitions for data storage.
Infrared Detection and Sensing: Deposited films enable fabrication of photodetectors and sensing elements sensitive to specific infrared wavelength bands.
Q1: What are the main characteristics of copper telluride thin films?
A1: They exhibit excellent thermoelectric properties, a narrow bandgap, and sensitivity to infrared light, making them suitable for energy conversion and detection applications.
Q2: Is the stoichiometric ratio (Cu:Te) of the target material adjustable?
A2: Yes, we can prepare target materials with different stoichiometric ratios, such as CuTe or Cu₂Te, according to your research or process requirements.
Q3: What are the requirements for the sputtering environment when using this target material?
A3: Controlled atmosphere is typically required, especially during reactive sputtering where precise control of reaction gas partial pressures (e.g., nitrogen, oxygen) is essential to obtain the target film.
Q4: How is its thermoelectric performance evaluated?
A4: Primarily by measuring the Seebeck coefficient, electrical conductivity, and thermal conductivity of the deposited film, ultimately calculating its figure of merit (ZT value).
