Peculiar electronic, strong in-plane and out-of-plane second harmonic generation and piezoelectric properties of atom-thick α-M2X3 (M = Ga, In; X = S, Se): role of spontaneous electric dipole orientations
Keyword(s):
Single- and few-layer α-M2X3 nanosheets exhibit out-of-plane SHG and piezoelectric properties, which can be tuned by switching spontaneous polarizations.
