This paper proposes and experimentally evaluates a novel oxide-free InP MIS structure having an ultra-narrow silicon surface quantum well. A theoretical calculation showed that the structure becomes free of gap states for silicon layer thicknesses below 5 Å. Experimentally, an ultra-narrow silicon surface quantum well was realized by direct nitridation of MBE Si layer by ECR N2 plasma and its detailed XPS analysis. A stable MIS structure with Nssmin=2×1010 cm-2 eV-1 was successfully realized
