There is an increasing reckoning that the thermoelectric performance of a material is dependent on its microstructure. However, the microstructure-properties relationship often remains elusive, in part due to the complexity of the hierarchy…
The recent PRB 73, 224501 (2006) henceforth referred as Ref.\cite{0} asserts that self-heating decreases with sample area reduction and claims to identify the intrinsic cause of ITS in submicrometre `mesa'. I will show that this assertion…
