Abstract: A device which detects and/or emits infrared radiation in the mid-infrared to far- infrared region is disclosed herein. The device comprises a first layer comprising a first transition metal dichalcogenide, and a second layer comprising a second transition metal dichalcogenide, wherein the second layer is deposited adjacent to the first layer to form a first interface which interlayer excitons are producible from for rendering the device operable to detect and/or emit infrared radiation in the mid-infrared to far-infrared region.
