Abstract

Recently, radio-frequency modulated reflectance (RMR) was proposed, as a novel method of modulation spectroscopy [1] and its advantage was shown at low temperatures with respect to traditional methods, such as photoluminescence (PL), electroreflectance and photoreflectance (PR). RMR principle is in the radio-frequency electric field effect on a light reflection from the structure. In this paper we show RMR spectra in Near-field configuration (NRMR) which demonstrate a dramatic change in the reflectance and a far lateral spread of NRMR perturbation.
