Abstract:
Magnetic and electronic nanomaterials have potentials for developing
new-generation electric devices to resolve power consumptions and
variability issues in today's microelectronics industry. In this
talk, I will present my recent research on the development of high
Curie temperature Mn0.05Ge0.95 quantum dots with
ferromagnetic order above room temperature. I will describe an approach
to probe the electric-field control of ferromagnetism in this material
(up to 300 K). I will also briefly discuss some of recent advance in
magnetotransport in graphene nanoribbons and voltage-controlled surface
states in topological insulator Bi2Te3. These
novel magnetic and electronic materials could be potentially used for
the long-sought power dissipationless applications.
