主权项

1. A device for conversion between thermal and electrical energy, comprising:
a thermoelectric source contact and a thermoelectric drain contact; and a material thermoelectrically connected at a first site to the source contact and at a second site to the drain contact, wherein the material comprises a plurality of folded 2-dimensional nanomembranes characterized by strong in-plane covalent bonding and weak bonding across the nanomembranes.
