The Effect of Collector Doping on InP-Based Double Heterojunction Bipolar Transistors
Doping InP-Based Double Heterojunction Bipolar Transistors
2009/7/28
High current effects on double heterojunction bipolar transistor (DHBT) performance were investigated. Three DHBTs with different collector doping densities were grown and processed. DC and RF measure...
Effects of Double Delta Doping on Millimeter and Sub-millimeter Wave Response of Two-Dimensional Hot Electrons in GaAs Nanostructures
Carrier mobility Delta doping Hot carriers Quantum wells
2010/2/2
Carrier mobility has become the most important
characteristic of high speed low dimensional devices. Due to
development of very fast switching semiconductor devices, speed of
computer and communica...
Enhanced Electrical Properties of p-type GaN by Mg Delta Doping
Mg-delta-doping p-type GaN hole mobility hole concentration
2010/7/16
The Mg-delta-doped GaN structure was grown by low-pressure metalorganic chemical vapor deposition (LP-MOCVD). The Hall-effect measurements revealed that the electrical properties were enhanced. A twof...
MOCVD-Grown InGa/GaAs Emitter Delta Doping Heterojunction Bipolar Transistors
Delta doping Heterojunction bipolar transistor
2010/12/7
The influence of delta doping sheet at base-emitter (BE) junction for an InGaP/GaAs heterojunction bipolar transistor (HBT) with a 75Å undoped spacer layer is investigated. A common emitter curr...
The Textural Effect of Cu Doping and the Electronic Effect of Ti, Zr and Ge Dopings Upon the Physical Properties of In2O3 and Sn-Doped In2O3 Ceramics
Cu In2O3 Sn-Doped In2O3 Ceramics
2010/12/16
The electronic properties of Cu-, Ti-, Zr-, and Ge-doped In2O3 (IO) and ITO (Sn-doped In2O3) ceramics are investigated. We distinguish the different effect of Cu doping (so called the “textural effect...
