Abstract


The Young's
modulus of thin conical InP nanowires with either wurtzite or mixed “zinc
blende/wurtzite” structures was measured. It has been shown that the value of
Young's modulus obtained for wurtzite InP nanowires (E[0001]=130 ± 30 GPa) was
similar to the theoretically predicted value for the wurtzite InP material (E[0001]=120
± 10 GPa). The Young's modulus of mixed “zinc blende/wurtzite” InP nanowires
(E[111]=65 ± 10 GPa) appeared to be 40% less then theoretically predicted value
for the zinc blende InP material (E[111]=110 GPa). An advanced method for
measuring the Young's modulus of thin and flexible nanostructures is proposed.
It consists of measuring the flexibility (the inverse of stiffness) profiles
1/k(x) by the scanning probe microscopy with precise control of loading force
in nanonewton range followed by simulations.
