Spin Selective Charge Transport through Cysteine Capped CdSe Quantum Dots
This work demonstrates
that chiral imprinted CdSe quantum dots (QDs) can act as spin selective
filters for charge transport. The spin filtering properties of chiral
nanoparticles were investigated by magnetic conductive-probe atomic
force microscopy (mCP-AFM) measurements and magnetoresistance measurements.
The mCP-AFM measurements show that the chirality of the quantum dots
and the magnetic orientation of the tip affect the current–voltage
curves. Similarly, magnetoresistance measurements demonstrate that
the electrical transport through films of chiral quantum dots correlates
with the chiroptical properties of the QD. The spin filtering properties
of chiral quantum dots may prove useful in future applications, for
example, photovoltaics, spintronics, and other spin-driven devices
