Not Accessible

Your library or personal account may give you access

Abstract

The room-temperature photoluminescence measurement has been used to characterize the optical properties of self-supporting InGaAs/GaAs microtubes. The PL show the intensity was enhanced for the self-supporting part comparing with the arm adhered to the substrate.
