Rolled-up In(Ga)As/GaAs Nanotubes Diameter as a Function of Structural Properties
Published online by Cambridge University Press: 01 February 2011
Abstract
Inherently strained bilayers of In(Ga)As/GaAs, Epitaxially grown on top of an AlAs sacrificial buffer layer roll-up into free-standing nanotubes if they are released from their substrate by selective underetching, Here, we preseant a systematic study of the tube diameter as a function of total bilayer thickness and the ratio between the two layer thinknesses. We show that the diameters of the tubes are well described by a continous mechanical model.
