abstract = {Currently, there is a growing interest in the development
of data storage devices and circuits based on
monocrystalline chalcogenides. They can be switched without
thermally initialized structural changes. The switching
consumes considerably less energy. However, the development
and optimization of such material systems calls for
alternative device processing and characterization
techniques. A novel nanostructure-transfer technique was
developed and will be reported with which epitaxially grown
Ge1Sb2Te4 platelets were transferred from their native Si
(111) substrate onto a sapphire-host substrate. The
freestanding Ge1Sb2Te4 platelets were fully integrated into
Ti/Au coplanar strip lines and electrically characterized.
The aim was to study intrinsic material attributes and
charge transport properties without any effect of the native
substrate nor influence and interaction of chemical products
needed in conventional lithographic processes. Highly
resistive switching was observed without any detectable
structural deterioration. Current densities exhibit values
from 10-6 down to 10-11A/µm3 at 1V bias switching. Our
study on freestanding Ge1Sb2Te4 platelets contributes to a
better understanding of charge transport related physical
phenomena in novel chalcogenides material systems.},
