Web14 Jul 2024 · In this work, we study the local crystal structure and strain relaxation at the atomic level in horizontal arrays of ZnSe@ZnTe core-shell nanowires grown on α-Al 2 O 3 (sapphire) substrates by ... Web2 Jun 2014 · The optical properties of catalyst-free AlN nanowires grown on Si substrates by molecular beam epitaxy were investigated. Such nanowires are nearly free of strain, with strong free exciton emission measured at room temperature. The photoluminescence intensity is significantly enhanced, compared to previously reported AlN epilayer.

Web19 Jul 2011 · It was found that the MgO nanowires appear more ductile at low strain rates, and the tensile strength decreases as the cross-sectional diameter decreases or temperature increases. However, the applied strain rates of 25 and 100 m/s may have resulted in very stiff and brittle mechanical response.
