Chinese team develops graphene-based heat-resistant memristors

A team of Chinese scientists has developed graphene-based high temperature-resistant memristors, which are leading candidates for future storage and neuromorphic computing, with potential to address existing challenges in the development of electronic devices.

The sandwich-like memristor is composed of two layers of graphene, with a layer of molybdenum disulfide in the middle. The memristor devices exhibit excellent thermal stability and can operate at a high temperature of up to 340 degrees Celsius.

"Most of these devices used in mobile phones and computers are subject to an operating temperature of below 125 degrees Celsius and may lead to miscalculation and data loss once the temperature passes the limit," said the leader the research team. This fact has limited the potential application of memristors in aerospace, military, and oil and gas industries.

"Traditionally, memristors running at high temperatures need a cooling system to guarantee smooth operations, but that increases the cost and energy consumption and lowers reliability," said the team.

While the research is still at the laboratory level, the researchers have already applied for patents in China and the United States.
