One-dimensional Material Showcases Exceptional Conductance


Published Date : May 02, 2018

Researchers from the University of California, Riverside, have revealed that an exotic material has the capability of conducting electricity 50 times more than conventional copper interconnection technology. As transistors in ICs continue to shrink in size, they present the need for higher conducting capabilities for effective performance. Most conventional conductors made of materials such as copper are likely to break under high current densities or due to factors such as overheating, creating barriers for further size reduction of electronic components.

Thus the need for effective alternatives to conventional conducting materials such as copper and silicon is pressing, especially in present times as nano-scale devices become the focus of research activities for the electronics industry. The research team from University of California, Riverside, seems to have made a promising development in this area. The researchers have discovered that nanoribbons made from a material called zirconium tritelluride (ZrTe3) possess high electricity conductance capability—one that largely exceeds that demonstrated by any other conventional materials used as conductors.

This strategy shifts focus of the research world from 2D conducting materials to 1D materials, a phenomenon that can prove to be an important development influencing the future generations of electronics devices and products. While conventional metals used as conductors are polycrystalline, meaning that they possess surface roughness and grain boundaries which can scatter electrons, one dimensional materials such as zirconium tritelluride have atomic chains of single crystal aligned in one direction. Researchers have attributed the high conductance of material to their single-crystal structure.
