Assignee: UNIVERSITY OF SOUTH CAROLINA
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C  Y | IPC H

Claim 0:
1. A voltage tunable solar-blind UV detector comprising:
a vertical bipolar transistor structure;
an upper epitaxial graphene emitter layer;
an intermediate p-SiC epilayer;
an n+SiC substrate layer;
the upper epitaxial graphene emitter laver, intermediate p-SiC epilayer and the n+SiC substrate layer are vertically stacked to form an:
epitaxial graphene/SiC heterojunction-based;
voltage tunable;
solar-blind;
UV detector with a peak wavelength responsivity shift from 320 nm to less than 250 nm dependent upon a bias voltage applied at the epitaxial graphene emitter layer.
