Claim 17:
18. A method of detecting physical properties using a resonant tunneling device that includes a first two-dimensional semiconductor layer, the first two-dimensional semiconductor layer including a first two-dimensional semiconductor material; a first insulating layer on the first two-dimensional semiconductor layer; and a second two-dimensional semiconductor layer provided on the first insulating layer and including a second two-dimensional semiconductor material of a same kind as the first two-dimensional semiconductor material, wherein a crystal lattice of the first two-dimensional semiconductor material and a crystal lattice of the second two-dimensional semiconductor material are aligned with each other, the method comprising:
causing the resonant tunneling device to detect one or more of a temperature, a wavelength of light incident on the resonant tunneling device, or an intensity of the light incident on the resonant tunneling device, based on a negative differential resistance (NDR) effect.
