ABSTRACT
We describe and experimentally demonstrate a method to create spin-polarized ballistic electrons through spin-orbit coupling in a two-dimensional electron system in an InSb/InAlSb heterostructure. Reflection of a spin-unpolarized injected beam from a lithographic barrier creates two fully spin-polarized side beams, in addition to an unpolarized specularly reflected beam. Antidot lattices were also fabricated in the InSb/InAlSb heterostructure. The temperature dependence of the antidot magnetoresistance from 0.4 K to 50 K was studied to characterize ballistic electron transport in InSb/InAlSb. © 2005 American Institute of Physics
