Growth and characterization of GaAs and InAs nano-whiskers and InAs/GaAs heterostructures
Publikation/Tidskrift/Serie: Physica E: Low-dimensional Systems and Nanostructures
Semiconducting InAs and GaAs nano-whiskers have been grown using a chemical beam epitaxy approach in combination with size-selected catalytic Au aerosol particles. The characterization of InAs and GaAs whiskers shows high crystalline quality as seen by transmission electron microscopy. Gate-dependent transport measurements suggests a diffusive electronic transport mechanism. We have also combined these two material systems by growing a very abrupt heterostructure interface within the whiskers, allowing the growth of highly mismatched structures without misfit dislocations.
