Sound waves may pave the way for topological electronic transistors. Researchers have designed and simulated the first topological acoustic transistors — with sound waves instead of electrons — and proposed a connection architecture to form a universal logic gate that can switch the flow of sound on and off.

Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics...

An electric car that runs on PV power sounds appealing. But is it really possible to enjoy flexibility with a vehicle charged through a home photovoltaic system? An ETH research team has reached some surprising conclusions.

The area of photovoltaics (PV) is rapidly increasing in popularity, and in Switzerland it already covers 5 percent of the country’s electricity consumption...

The field of self-repairing materials is rapidly expanding, and what used to be science fiction might soon become reality, thanks to scientists who developed eco-friendly nanocrystal semiconductors capable of self-healing. Their findings describe the process, in which a group of materials called double perovskites display self-healing properties after being damaged by the radiation of an electron beam.

From the Terminator to Spiderman’s suit, self-repairing robots and devices abound in sci-fi movies. In reality, though, wear and tear reduce the effectiveness of electronic devices until they need to be replaced...
