InGaP/GaAs/InGaP double-heterojunction bipolar transistors grown by solid-source molecular-beam epitaxy with a valved phosphorus cracker

چکیده
The growth and device characterization of an InGaP/GaAs double-heterojunction bipolar transistor is reported, the device is grown in a solid source molecular beam epitaxy system equipped with a valved phosphorus cracker. Various designs of base–collector (B–C) junction are used to eliminate the current blocking effect caused by the conduction band discontinuity. The results show that a chirped superlattice with a delta-doping layer at the B–C junction has the best dc characteristics. Both dc and microwave results of these devices are comparable to those obtained with other advanced growth techniques. © 1996 American Vacuum Society.

Operation and device applications of a valved-phosphorus cracker in solid-source molecular-beam epitaxy
Solid phosphorus is successfully incorporated into a molecular-beam epitaxy system by a valved-cracker for the growth of phosphorus-based materials. The operating parameters are established through beam flux and reflection high-energy electron diffraction measurements. InP and InGaP lattice matched to GaAs were grown and characterized by Hall measurements, photoluminescence, electroreflectance,...
متن کاملInAs=InGaP=GaAs heterojunction power Schottky rectifiers
A low-temperature (LT) grown InAs epi-layer has been applied as the gate to the dual-material structure of lattice-matched InGaP on GaAs, to make a high-temperature power rectifier. The LT molecular beam epitaxy technique enables the formation of an abrupt interface between InAs and InGaP. This heterojunction rectifier utilises the strong thermal stability of the InAs=InGaP heterojunction and t...

Heterojunction bipolar transistors with GaAsxP1-x bases and collectors and InyGa1-yP emitters were grown on GaAs substrates via metalorganic chemical vapor deposition (MOCVD), fabricated using conventional techniques, and electrically tested. Four different GaAsxP1-x compositions were used, ranging from x = 0.825 to x = 1 (GaAs), while the InyGa1-yP composition was adjusted to remain lattice-ma...

InGaAsSb/InP Double Heterojunction Bipolar Transistors Grown by Solid-Source Molecular Beam Epitaxy
The DC and RF characteristics of double heterojunction bipolar transistors (DHBTs) with a compressively strained InGaAsSb base prepared by solid-source molecular beam epatixy (MBE) are investigated. Compared with conventional InGaAs/InP DHBT structures, the proposed InGaAsSb/InP HBT exhibits lower baseemitter turn-on voltage and VCE-offset voltage. Also observed are the high collector current d...
