Abstract
A complementary heterojunction semiconductor device (10) has a first resonant interband tunneling transistor (12) coupled to a second resonant interband tunneling transistor (14) through a common output (16). The first transistor (12) has a first gate (18) of a first semiconductor type and a drain (28) coupled to the first gate (18). The first gate (18) is also coupled to the common output (16). The second transistor (14) has a second gate (32) of a second semiconductor type and a source (42) coupled to the second gate (32). The second gate (32) is also coupled to the common output (16). The valence band (60,80,82) of the first semiconductor type has an energy level greater than the conduction band (62,64,84) of the second semiconductor type.
