We have developed a numerical technique for calculating inhomogeneous strai
ns in stressed semiconducting nanostructures, such as quantum wires and dot
s manufactured by nanolithography from stressed InGaAs/GaAs quantum wells.
The technique is based on solving a linear problem of elasticity theory by
the Green's function method and presumes a lack of defects and dislocations
in nanostructure heterojunctions. Spatial distributions of strain tensor c
omponents and shifts of electron and hole potentials in a nanostructure due
to the strain have been calculated. (C) 1999 American Institute of Physics
