The R2E project at CERN has tested a few commercial SRAMs and custom-designed SRAM, whose data are complementary to various scientific publications. experimental include low- high-energy protons, heavy ions, thermal, intermediate- neutrons, electrons pions.
GaN high-electron-mobility transistors (HEMTs) are promising next-generation devices in the power electronics field which can coexist with silicon semiconductors, mainly some radiation-intensive environments, such as space converters, where high frequencies and voltages also needed.
