▎ 摘　　要

NOVELTY - The detector has a graphene surface formed on a silicon substrate, where resistivity of the silicon substrate is about 1-10 ohm cm. A metal electrode is located on a rear surface of the silicon substrate. The graphene surface is formed with a single-graphene layer and a dual-graphene layer. An upper part of the metal electrode is contained with gold, nickel or platinum. USE - Graphene-silicon hetero-junction based passive position sensitive detector. ADVANTAGE - The detector can obtain graphene-based hetero-junction silicon, increase working wavelength and reduce power consumption rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-silicon hetero-junction based passive position sensitive detector manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene-silicon hetero-junction based passive position sensitive detector. '(Drawing includes non-English language text)'
