Binding energy of exciton complexes determined by the tunneling current of single electron transistor under optical pumping
David M T Kuo, Yia-chun chang
We theoretically study the tunnelling current of a single electron transistor (SET) under optical pumping. It found that holes in the quantum dot(QD) created by optical pumping lea…

Spontaneous spin polarized tunneling current through a quantum dot array
David M. -T. Kuo, Y. -C. Chang
We show theoretically that a strongly spin-polarized current can be generated in semiconductors by taking advantage of the ferromagnetic phase of a quantum dot array (QDA). A Hubba…
