What is RoHS Compliance? RoHS stands for Restriction of Hazardous Substances. It is a directive that was introduced by the European Union (EU) in 2003 to restrict the use of certain hazardous substances in electrical and electronic equipment (EEE). The directive aims to protect human health and the environment by […]

Introduction to Semiconductors Before diving into the details of hole density, let’s briefly review some basics of semiconductors. A semiconductor is a material that has electrical conductivity between that of a conductor (like metals) and an insulator (like glass). The most common semiconductor materials are silicon (Si) and germanium (Ge). […]
