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...
