▎ 摘　　要

NOVELTY - The device has a terahertz wave generating unit (1) provided with a metal-medium-metal waveguide (2). The terahertz wave generating unit is connected with a first silicon dioxide layer (6). A first graphene layer (7) is connected with a first drain (8). A FET probing unit (3) is provided with a second silicon dioxide layer (10). Metal blocks (9) are arranged above a first source electrode (17). A second source electrode (15) is arranged on the second graphene layer (11). A lock phase amplifier (4) is connected with the first source electrode and a second drain (12). USE - Graphene terahertz source and detector based cancer cell spectrum analysis device. ADVANTAGE - The device has wide application potential.
