Molecular Electronics All Set to Silicon Chips

Researchers have introduced a non-invasive, scalable and rapid method for expanding CNTs on a plane substrate. Such breakthrough could aid usher in the day when electronic molecular replaces silicon chips as the core elements of electronics.

CNT’s or Carbon Nanotubes have long interested researchers because of their extraordinary optical, electrical, mechanical and thermal properties and chemical sensitivity. But significant challenges remain before CNTs can be executed on a big scale, containing the requirement to generate them in particular locations on a plane substrate, in situations that will result in the creation of a circuit around them.

Headed by Professor Yuval Yaish of the Witerbi Faculty of Electronic Engineering and the Zisapel Nanoelectronics Centre at the Technion, the scientists have introduced a technology that addresses such hassles. Their discovery also makes it feasible to investigate the dynamic properties of CNTS, containing resonance, acceleration and the transformation from softness to hardness.

The technique could be used as a suitable platform for the combining of silicon technologies with nano-electronics, and possibly even with the removal of such technologies in molecular electronics.

“The CNT is a spectacular and highly robust building block with extraordinary mechanical, optical and electrical properties,” says Professor Yaish. “Some of them are conductors while few are semi-conductors, which is why they are seen as an upcoming replacement for silicon. But present techniques for the generation of CNTs are expensive, slow and imperfect. As such, they truly cannot be executed in the industry.

Due to the size of the nanometer of the CNTs, it is highly difficult to locate or find them particular locations. Professor Yaish, and graduate students Michael Shlafman and Gilad Zeevi, introduced a rapid, non-invasive, simple and scalable method that allows optical imaging CNTs. Despite depending upon the chemical properties of CNT, it is a both physical and chemical defect on the otherwise uniform and flat surface. It can cater as an implantation for the nucleation otherwise uniform and flat surface. It can cater as a seed for the nucleation and growth of minute, but optically visible microscope, because of their tiny size and are these, are too small to be seen in this way.

Since the surface of the CNT is not utilized to link the molecules, they can be eradicated after imaging and leaving the surface intact and restore the mechanical and electrical properties of CNT.

“Our tactic is the opposite of the custom,” he continued. “We expand the CNTs directly and with the support of the organic crystals that layer them, we can identify them with the use of a microscope very instantly. Then identification of image software discovered and produced the gadget – transistor. Such technique aims to incorporate CNTs into an assimilated circuit of miniaturized electric components (specifically transistors) on one sole chip.

Such could cater as a replacement for silicon based electronics. Professor Yaish also claimed that the potential to describe this principle and generate world-class gadgets was made feasible by the specific infrastructures obtainable at the Technion clean room facilities in the Wolfson Microelectronics Center, led by Professor Nir Tessler.
