Caption

(a) Measured DC photocurrent I as a function of VL and VR at VSD = 0 V while applying an MW signal at f = 3.81 GHz with a power of PRF = ?14 dBm. Dashed lines locate the CNPs in the left and right regions taken from the conductance measurement in Figure 1c. (b,c) Photocurrent line traces taken for VL = ?10 V (trace A) and VR = ?10 V (trace B). Dashed arrows in b and c indicate the CNP. (d) Dependence of the photocurrent on the MW power P applied at room temperature measured in the bipolar p?n regime for VL = ?10 and VR = 10 V in log?log representation.23 The black line corresponds to I ? P.
