We also report cross-plane thermoelectric measurements of SnSe and SnSe2 films grown by the modulated element reactant (MER) approach. By performing post-growth annealing at a fixed Se partial pressure, a transition from SnSe-to-SnSe2 is induced which results in a 16-fold increase (from -38.6 to -631µV/K) in the cross-plane Seebeck coefficient.2
