Rare element to provide better material for high-speed electronics

West Lafayette, IN | Posted on May 30th, 2018

The discovery adds to a list of extremely thin, two-dimensional materials that engineers have tried to use for improving the operation speed of a chip's transistors, which then allows information to be processed faster in electronic devices, such as phones and computers, and defense technologies like infrared sensors.

Other two-dimensional materials, such as graphene, black phosphorus and silicene, have lacked either stability at room temperature or the feasible production approaches required to nanomanufacture effective transistors for higher speed devices.

"All transistors need to send a large current, which translates to high-speed electronics," said Peide Ye, Purdue's Richard J. and Mary Jo Schwartz Professor of Electrical and Computer Engineering. "One-dimensional wires that currently make up transistors have very small cross sections. But a two-dimensional material, acting like a sheet, can send a current over a wider surface area."

Tellurene, a two-dimensional film researchers found in the element tellurium, achieves a stable, sheet-like transistor structure with faster-moving "carriers" - meaning electrons and the holes they leave in their place. Despite tellurium's rarity, the pros of tellurene would make transistors made from two-dimensional materials easier to produce on a larger scale. The researchers detail their findings in Nature Electronics.

"Even though tellurium is not abundant on the Earth's crust, we only need a little bit to be synthesized through a solution method. And within the same batch, we have a very high production yield of two-dimensional tellurene materials," said Wenzhuo Wu, assistant professor in Purdue's School of Industrial Engineering. "You simply scale up the container that holds the solution, so productivity is high."

Since electronics are typically in use at room temperature, naturally stable tellurene transistors at this temperature are more practical and cost-effective than other two-dimensional materials that have required a vacuum chamber or low operation temperature to achieve similar stability and performance.

The larger crystal flakes of tellurene also mean less barriers between flakes to electron movement - an issue with the more numerous, smaller flakes of other two-dimensional materials.

"High carrier mobility at room temperature means more practical applications," Ye said. Faster-moving electrons and holes then lead to higher currents across a chip.

The researchers anticipate that because tellurene can grow on its own without the help of any other substance, the material could possibly find use in other applications beyond computer chip transistors, such as flexible printed devices that convert mechanical vibrations or heat to electricity.

"Tellurene is a multifunctional material, and Purdue is the birthplace for this new material," Wu said. "In our opinion, this is much closer to the scalable production of two-dimensional materials with controlled properties for practical technologies."
