Single electron transistor based on ordered mesoporous and preparation thereof

Abstract

The invention discloses a single-electron transistor based on ordered mesopores and the fabrication method thereof, which can solve the problems of the prior single-electron transistors, such as large quantum dot size, disordered arrangement of the quantum dots and poor isolation performance of the quantum dots. The single-electron transistor based on ordered mesopores consists of a substrate, a source, a drain, a gate and an ordered mesopore layer and an insulation layer, wherein nanoparticles serving as the quantum dots of the single-electron transistor are assembled in the ordered mesopores of the ordered mesopore layer. The fabrication method comprises the following steps: preparing the substrate; then fabricating the ordered mesopore layer, the source and the drain; fabricating the insulation layer next; and finally fabricating the gate. With the adoption of the method, quantum dots with the size of 0.5 to 0.8 nm and ordered arrangement, so that the single-electron transistor can operate at normal temperature with the advantages of high reliability and convenient fabrication and integration.

Description

technical field [0001] The invention relates to a single-electron transistor and a preparation method thereof, in particular to a single-electron transistor based on ordered mesopores and a method for preparing the device by using nanometer chemical and physical processing methods. Background technique [0002] Integrated circuits with metal-oxide-semiconductor field-effect transistor (MOSFET) devices as the mainstream have been developing rapidly following Moore's law. The minimum feature size of the current MOSFET has reached 65nm. As the feature size enters the nanometer level, MOSFETs exhibit strong quantum effects, and logic functions are severely challenged. Therefore, it is imminent to develop electronic logic devices that can work normally at the nanoscale, and has become a research hotspot in the field of integrated circuit manufacturing. [0003] Single-electron transistors have the advantages of small size, fast speed, low power consumption, and large-scale inte...
