Abstract-Heterostructured hBN-BP-hBN Nanodetectors at Terahertz Frequencies

By reassembling the thin isolated atomic planes of hexagonal borum nitride (hBN) with a few layer phosphorene (black phosphorus BP), hBN/BP/hBN heterostructures were mechanically stacked to devise high efficiency THz photodetectors operating in the 0.3–0.65 THz range, from 4K to 300K, with a record signal-to-noise ratio of 20000.
