Twinning superlattices in indium phosphide nanowires

, 2008
Here, we show that we control the crystal structure of indium phosphide (InP) nanowires by impurity dopants. We have found that zinc decreases the activation barrier for 2D nucleation growth of zinc-blende InP and therefore promotes the InP nanowires to ...

Relevance of the purity level in a MetalOrganic Vapour Phase Epitaxy reactor environment for the growth of high quality pyramidal sitecontrolled Quantum Dots

, 2010
We report in this work on the spectral purity of pyramidal site-controlled InGaAs/AlGaAs Quantum Dots grown by metalorganic vapour phase epitaxy on(111)B oriented GaAs substrates. Extremely sharp emission peaks were found, showing linewidths surprisingly

Nitride MOVPE tops the bill

III-Vs Review, 1999
AbstractThe predominance of activity in the nitrides field and the emergence of in situ monitoring into mainstream metal organic vapour phase epitaxy were among the themes of the 8th European Workshop on MOVPE. The location of Prague close to the geographical centre of the united Europe did much to encourage participation from all corners of the ...

Low-Threshold Electrically Pumps Vertical-Cavity Surface-Emitting Microlasers [PDF]

, 1989
Vertical-cavity electrically driven lasers with three GaInAs quantum wells and diameters of several μm exhibit room-temperature pulsed current thresholds as low as 1.3mA with 958 nm output ...
