▎ 摘　　要

NOVELTY - The detector has a first layer formed as a substrate (1). A second layer is formed as graphite (2). A planar opening ring antenna (3) is connected to a graphene source (4) that is connected with an antenna and a drain electrode (5). A third layer is formed as a medium layer (6). A fourth layer is formed as a gate (7). The substrate is provided with a silicon dioxide layer. The planar opening ring antenna, graphene source and the drain electrode are provided with two layers of a metal layer, where lower metal layer is chromium and upper metal layer is gold and alumina. The gate is provided with the lower metal layer and the upper metal layer. USE - Controllable room temperature graphene terahertz detector. ADVANTAGE - The detector regulates concentration and speed of carriers in the graphene by a terahertz modulation electric-field, and generates a direct current response signal. The detector has high speed, wide frequency and high response rate, which can realize double modulation of source-drain bias and gate voltage, and lays a foundation for large-scale application of room temperature terahertz detector. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a controllable room temperature graphene terahertz detector manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a controllable room temperature graphene terahertz detector.
