It bonds with its silicon neighbor atoms, but one electron is not involved in bonding. Instead, it is free to move inside the silicon structure. A solar cell consists of a layer of p-type silicon ...

Geologists can tell a chalcedony from the arrangement and structure of its ... mineral called beryl whose chemical formula is a complex mix of beryllium, aluminum, silicon, and oxygen.

It can only add single bits at a time and is limited to kilohertz clock speeds, but it is capable of executing the full RISC-V 32-bit instruction set thanks to nearly 6,000 individual transistors.

Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may ...

Their solar cells reached a power conversion efficiency (PCE) of 26.3%, a result that rivals commercial silicon cells. This record-setting performance was officially recognized by the U.S. National ...
