Auginash. April 20, 2015. Abstract. High electron mobility transistor(HEMT) is a transistor that operates at higher frequencies, typically in the microwave range. They are used in applications that require high frequency, such as cell phones, RF applications, and some power applications. HEMTs are transistors that utilize the 2-dimensional electron gas(2DEG) created by a junction between two materials with different band gaps called a heterojunction. The two most commonly used materials to create the heterojunction are a highly doped n-type donor material, typically . a brief overview. Montek Singh. Feb . {7. , 12}. , 2018.
