The crystal structure at the surface of semiconductor materials can make them behave like metals and even like superconductors, a joint Swansea/Rostock research team has shown. The discovery potentially opens the door to advances like more energy-efficient electronic devices. Semiconductors are the active parts of transistors, integrated circuits, sensors, and LEDs. These materials, mostly based on silicon, are at the heart of today’s electronics industry.

In a report published in NANO, scientists from the Jiangxi University of Science and Technology, Guangdong University of Petrochemical technology, Gannan Medical University and Nanchang Hangkong University in China underline the importance of defect engineering to promote catalytic performance by providing a simple and efficient way for modifying and optimizing metal-free semiconductor photocatalyst graphitic carbon nitride (g-C3N4) to solve the dual problems of environmental pollution and lack of fossil resources.
