New nanomesh material created: Silicon-based film may lead to efficient thermoelectric devices

Computers, light bulbs and even people generate heat -- energy that ends up being wasted. Thermoelectric devices, which convert heat to electricity and vice versa, harness that energy. But they're not efficient enough for widespread commercial use or are made from expensive or environmentally harmful rare materials. Researchers have just developed a new type of material -- a nanomesh, composed of a thin film with a grid-like arrangement of tiny holes -- that could lead to efficient thermoelectric devices.
