Nanogap structures for molecular nanoelectronics

Nanogap structures for molecular nanoelectronics

This study is focused on the realization of nanodevices for nano and molecular electronics, based on molecular interactions in a metal-molecule-metal (M-M-M) structure. In an M-M-M system, the electronic function is a property of the structure and can be characterized through I/V measurements. The contact between the metals and the molecule was obtained by gold nanogaps (with a dimension of les...

Molecular Nanoelectronics: A future perspective

The conventional VLSI technology based on lithography is reaching its limits and the extension of Moore’s Law for small-scale conventional silicon based integrated circuits is gaining significance. Developments in the area of molecular electronics devices offer an alternative approach to overcome this problem and have the potential to miniaturize the computational devices down to few nm. This i...

Formation of Molecular-Scale Gold Nanogap Junctions via Controlled Electromigration

We have used a feedback method to control the electromigration of gold nanowires to form nanogap junctions, similar to recent reports [1, 2]. We have studied gold wires fabricated with conventional electron-beam and photolithography on thick SiO2 and thin Al2O3 (over Al) substrates. We find that the role of feedback mechanism is to control the local temperature of the electromigrating nanowire,...

Technology Roadmap for Nanoelectronics

Nanotubes for Nanoelectronics

Carbon nanotubes (CNTs) have emerged as a viable electronic material for molecular electronic devices because of their unique physical and electrical properties [1–7]. For example, nanotubes have a lightweight and record-high elastic modulus, and they are predicted to be by far the strongest fibers that can be made. Their high strength and high flexibility are unique mechanical properties. They...
