Figure 1

Schematic image of the theory of the two-probe measurement. Excited carriers generated by local excitation at arbitrary points using a sharpened probe diffuse in the sample. The detection of carriers after transportation is performed locally using an observation probe and take each spectrum. In this way, the local carrier density of the carriers diffused in the sample can be directly measured.
