Achieving high thermoelectric performance through constructing coherent interfaces and building interface potential barriers in n-type Bi2Te3/Bi2Te2.7Se0.3 nanocomposites

Although Bi2Te2.7Se0.3 is the best n-type thermoelectric material near room temperature, its energy-conversion efficiency η reported so far is still low. Hence, it is imperative to increase its η so as to realize widespread applications in heat recovery. Here, we show that through incorporation of B...
