Originální abstrakt

We report near field optical beam induced current (NOBIC) measurements on semiconductor quantum well (QW) structures. A sub-wavelength fiber tip is coupled with a tunable laser source and scanned over a sample surface. The induced photocurrent reveals the compositional profile of quantum structures. We demonstrated that the resolution of this technique depends strongly on the aperture size.
