Tailoring thermoelectric materials for specific designs and applications has been gaining momentum during past three decades. Initially confined to conventional (bulk) framework an entirely new scenario emerged with inclusion of low-dimensional structures in the scheme of things. The paper...

A simple electronic experiment using a field-effect-transistor–type microstructure is suggested. The thin superconductor layer forms the source-drain channel of a layered structure across which an AC current is applied. It is found necessary to measure the second harmonic of the source-gate...
