	1	Photo-Induced Spin Dynamics in Nanoelectronic Devices显示文摘The present research is devoted to the investigation of electron spin transmission through a nanoelectronic device.This device is modeled as nonmagnetic semiconductor quantum dot coupled to two diluted magnetic semiconductor leads.The spin transport characteristics through such a device are investigated under the effect of an ac-field of a wide range of frequencies.The present result shows a periodic oscillation of the conductance for both the cases of parallel and antiparallel spin alignment.These oscillations are due to Fano-resonance.Results for spin polarization and giant magneto-resistance show the coherency property.The present research might be useful for developing single spin-based quantum bits(qubits)required for quantum information processing and quantum spin-telecommunication.

	2	Fano Factor in Strained Graphene Nanoribbon Nanodevices显示文摘We investigate the Fano factor in a strained armchair and zigzag graphene nanoribbon nanodevice under the effect of ac fheld in a wide range of frequencies at different temperatures(10 K-70 K). This nanodevice is modeled as follows: a graphene nanoribbon is connected to two metallic leads. These two metallic leads operate as a source and a drain. The conducting substance is the gate electrode in this three-terminal nanodevice. Another metallic gate is used to govern the electrostatics and the switching of the graphene nanoribbon channel. The substances at the graphene nanoribbon/metal contact are controlled by the back gate. The photon-assisted tunneling probability is deduced by solving the Dirac eigenvalue differential equation in which the Fano factor is expressed in terms of this tunneling probability. The results show that for the investigated nanodevice, the Fano factor decreases as the frequency of the induced ac fheld increases, while it increases as the temperature increases.In general, the Fano factors for both strained armchair and zigzag graphene nanoribbons are different. This is due to the effect of the uniaxial strain. It is shown that the band structure parameters of graphene nanoribbons at the energy gap, the C-C bond length, the hopping integral, the Fermi energy and the width are modulated by uniaxial strain. This research gives us a promise of the present nanodevice being used for digital nanoelectronics and sensors.	Walid Soliman Mina D.Asham Adel H.Phillips	2017	Chinese Physics Letters2017，34，11：	0
