DEVELOPMENT OF HIGH POWER NPN GAN/INGAN DOUBLE- HETEROJUNCTION BIPOLAR TANSISTOR Final Report
The Georgia Tech team developed state-of-the-art GaN heterojunction bipolar transistor (HBT) technology in this NSF program. Throughout the project period, baseline device fabrication and material growth techniques were actively studied and significant technological advancement was achieved in III-Nitride (III-N) HBT research. We successfully demonstrated high-current gain (> 100) InGaN HBT on ...
متن کاملGaAs Heterojunction Bipolar Transistor Emitter Design
We demonstrate that GaAs-based HBTs with very low base currents at both low and high injection levels can be achieved using either Al0.35Ga0.65As or InGaP in the emitter with the proper optimization of structure and growth. We observe an order of magnitude reduction in space charge recombination current as the Al composition, and hence the energy-gap, of the emitter increases from 25% (1.77 eV)...
متن کاملToward complementary ionic circuits: the npn ion bipolar junction transistor.
Many biomolecules are charged and may therefore be transported with ionic currents. As a step toward addressable ionic delivery circuits, we report on the development of a npn ion bipolar junction transistor (npn-IBJT) as an active control element of anionic currents in general, and specifically, demonstrate actively modulated delivery of the neurotransmitter glutamic acid. The functional mater...
متن کاملSimulation of electrical characteristics of InP/In0.24Ga0.76As0.73Sb0.27/In0.53Ga0.47As double heterojunction bipolar transistor
The electrical characteristics of InP/In0.24Ga0.76As0.73Sb0.27/In0.53Ga0.47As double heterojunction bipolar transistor (DHBT) are investigated. The study is based on energy balance (EB) transport model and TCAD SILVACO device simulator. InP/In0.24Ga0.76As0.73Sb0.27 DHBT have a low Emitter-Base conduction band discontinuity EC and a minimum base bandgap energy EG among the entire composition ran...
متن کاملAn enhanced model for InGaP/GaAs heterojunction bipolar transistor
This paper presents an improved InGaP/GaAs heterojunction bipolar transistor (HBT) model based on the Vertical Bipolar Inter-Company (VBIC) model. New transport current expression is proposed by considering the heterojunction effect. Collector capacitance is developed due to the mobile charge modulation, and the transit time formula is improved to account for electron velocity variation with th...
