Conductance,I−Vcurves, and negative differential resistance of carbon atomic wires

The structures and electrical transport properties of germanium nanowires encapsulated in carbon nanotubes

“…Usually, I-V curves can be measured by experimental methods which show nonlinear behavior. 17,18 Studies of semiconductor nanowires are of particular interest 19 because their properties make them good potential candidates in the development of nanoelectronic devices. Despite these progresses, the formation mechanism and the correlation between the atomic structures and transport properties of atomic-sized nanowires are still insuffia͒ Electronic mail: lihuilmy@hotmail.com JOURNAL OF APPLIED PHYSICS 102, 073709 ͑2007͒ cient.…”

Spin-dependent transport through a magnetic carbon nanotube-molecule junction

“…Due to their importance as potential building blocks for the next-generation molecular/ nano-engineered electronic devices, understanding electronic transport through CNTs 13,14 and individual molecule 15,16 ͑and references therein͒ has become the focus of nanoelectronics research in recent years. Although spin-independent transport in both metal-CNT-metal [17][18][19][20] and metal-molecule-metal [21][22][23][24][25] junctions have been extensively studied theoretically, theoretical work on spin-dependent transport is more limited, 26,27 particularly in CNT-molecule-CNT junctions. 9,28 There have been many proposals for building electronic devices using single molecules 15,16 ͑and references therein͒.…”

CrAs(001)/AlAs(001) heterogeneous junction as a spin current diode predicted by first-principles calculations

“…Hence, the strong diode effect of majority spin current is presented. The transmission coefficients that entered the bias voltage window originate from the couple of bands of CrAs around the Fermi level and the tail of the bottom of conductance band of AlAs, because of the electrochemical potential shift under the application of bias voltage in electrodes, which result in the shifting of the Fermi levels correspondingly, as well as the contribution of charge-transfer doping [11].
