Enhancing thermoelectric performance of GeSb4Te7 single crystals through synergistic band and point defect engineering

GeSb4Te7, a quasi-two-dimensional semiconductor, exhibits high potential in thermoelectric applications. Herein, efficacious Yb/In co-doping has been realized in the GeSb4Te7 single crystals prepared by the slow-cooling method to enhance their thermoelectric properties. DFT calculations demonstrate...
