Previously we showed that the thermoelectric (TE) performance of bulk n-type Bi<sub>2</sub>Te<sub>2.7</sub>Se<sub>0.3</sub> can be enhanced by subjecting it to a combined process of chemical or mechanical exfoliation (C/ME) followed by a rapid densification and restacking of the exfoliated layers via the spark-plasma-sintering technique (SPS). Here, we present a systematic micro-Raman study of two-dimensional flakes of n-type Bi<sub>2</sub>Te<sub>2.7</sub>Se<sub>0.3</sub> produced by the C/ME pr ...[more]
