n Bu 2 Sn(S n Bu) 2 and n Bu 3 SnE n Bu (E = S or Se) – effective single source precursors for the CVD of SnS and SnSe thermoelectric thin films

LPCVD with the title compounds produces S-deficient SnS, or stoichiometric, semiconducting, resistive SnS or SnSe films with large positive Seebeck coefficients and an SnSe power factor of 0.4 μW cm −1 K −2 at 425 K.
