Abstract
A terahertz wave detecting apparatus includes a semiconductor chipin which a 2-dimensional electron gasis formed at a constant position from its surface, and a carbon nanotube, a conductive source electrode, a drain electrodeand a gate electrodeprovided in close contact with the surface of the chip. The carbon nanotubeextends along the surface of the chip, where both ends of the tube are connected to the source electrode and the drain electrode of the chip, and the gate electrodeis spaced at a constant interval from the side surface of the carbon nanotube. Further, the apparatus includes a SD current detecting circuitfor applying a voltage between the source electrode and the drain electrode and for detecting SD current therebetween, a gate voltage applying circuitfor applying a variable gate voltage between the source electrode and the gate electrode, and a magnetic field generating devicefor applying a variable magnetic field to the chip.
