Investigations of the Fabricated Nothing On Insulator Nanodevices as Metal-Air-Metal variant - NOI-MAM

ABSTRACT: This paper presents some investigations of an experimental Nothing On Insulator device, made in the Metal-Air-Metal (NOI-MAM) variant. The vacuum nanodevices are potential candidates for tera-Hertz applications. The investigations concern the fabrication processes, measurements of the output characteristics and simulations of the NOI-MAM devices. Two metallic nanowires are considered instead of two semiconductor nano-islands for Source and Drain. Air molecules in normal conditions inside a gap of maximum 36 nm size represents the “Nothing” area. The electron-beam lithography technology or AFM sectioning by tips are investigated by SEM and AFM analysis. The measured and simulated current-voltage curves are investigated for potential applications.

KEYWORDS: Nanotechnology; Metallic nanowires; electron-beam lithography; vacuum devices; SEM, AFM
