GaAs 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 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 کاملAnalysis of Kirk Effect in Nanoscale Quantum Well Heterojunction Bipolar Transistor Laser
In this paper, we present an analytical model to analysis the kirk effect onstatic and dynamic responses of quantum well heterojunction bipolar transistor lasers(HBTLs). Our analysis is based on solving the kirk current equation, continuityequation and rate equations of HBTL. We compare the performance (current gain,output photon number and small signal modulation bandwi...

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...
