Anne L. Frances,Adam B. Smith,Colin K. Khouryracteristic energy is the threshold energy for impact ionization .. which is of the order of the bandgap ... A carrier possessing this energy can transfer its energy via collision to an electron in the valence band and move it into the conduction band. In this process, which is called impact ionizat

Wild Plant Genetic Resources in North America: An Overviewber of these have become globally important domesticated crops, including maize, beans, cotton, and sunflower. Many other native and also naturalized species have potential for use, either directly or as genetic resources for breeding agricultural crops. However, despite increasing recognition of th
