Sino-German
joint research team through the study for the first time to prove the
incorporation of cobalt elements in zinc oxide made of nano-wire, can
make nano-wire with intrinsic magnetic. This result is important for the development of new magnetic
semiconductor materials with high computational speed and low energy
consumption.
Sino-German
joint research team through the study for the first time to prove the
incorporation of cobalt elements in zinc oxide made of nano-wire, can
make nano-wire with intrinsic magnetic. This result is important for the development of new magnetic
semiconductor materials with high computational speed and low energy
consumption.
Since
the 1990s, physicists have been trying to develop magnetic
semiconductors with intrinsic magnetic properties. Spin electronics with
this semiconductor material can greatly improve computational power and
significantly reduce energy consumption. It
has been known to scientists that the incorporation of magnetic ions
into non-magnetic compound semiconductors can form a novel functional
material, which is a semiconducting semiconductor with both
semiconducting properties and magnetic properties, but it is not clear
how this magnetism has spin electrons Use the required intrinsic nature.
In
this study, researchers at the University of Jena in Germany
incorporated cobalt elements into nanowires made of zinc oxide;
researchers at the Chinese University of Hong Kong, China, conducted a
sample using transmission electron microscopy and electronic magnetic
circular dichroism Analysis, the results found that the incorporation of cobalt elements
of the sample with intrinsic magnetic properties, and doped iron element
of the nano-wire is not intrinsic magnetic.
Researchers
at the Chinese University of Hong Kong, China, said that magnetic
semiconductor nanomaterials are still in the research stage, but in the
near future, this result may open the door to the practical application
of magnetic semiconductor nanomaterials.
