Besides its interesting physical properties, graphene as a two-dimensional lattice of carbon atoms promises to realize devices with exceptional electronic properties, where freely suspended graphene without contact to any substrate is the ultimate, truly two-dimensional system. The practical realization of nano-devices from suspended graphene, however, relies heavily on finding a structuring me...

In this paper, we study the effect of single Boron/Nitrogen impurityatom on electronic properties of a silicene nano flake. Our calculations are basedon density functional theory by using Gaussian package. Here, one Si atom insilicene nano flake substitutes with a Boron/Nitrogen atom. The results show thatsubstitution of one Si atom with single Boron/Nitrogen atom increases distanceof impurity ...

The rapid development of numerous microscale electronic devices, such as smart dust, micro or nano bio-sensors, medical implants and so on, has induced an urgent demand for integratable micro or nano battery supplies with high energy and power densities. In this work, 3D hexagonal bottle-like Si/Ge composite nanorod (NR) array electrodes with good uniformity and mechanical stability potentially...

The miniaturization of nano-scale electronic devices, such as metal oxide semiconductor field effect transistors (MOSFETs), has given rise to a pressing demand in the new theoretical understanding and practical tactic for dealing with quantum mechanical effects in integrated circuits. Modeling and simulation of this class of problems have emerged as an important topic in applied and computation...

Molecules are attractive to develop nano-electronic devices. In this paper a new type of transistor is realized by using self-organized films of the Guanosine molecule, a modified DNA base. With its 40 nm channel length the transistor is a good starting point for a new class of nano-electronics devices. Experimental current-voltage characteristics are shown. A circuital model is also proposed. ...

Organic electronic devices are becoming increasingly important in a wide variety of applications. These nano-structured devices are typically composed of complex thin/ultrathin multilayers of novel organic or organometallic compounds, along with inorganic materials. The overall electronic behavior of these devices is strongly influenced by the electronic properties and chemical compositions of ...

 The two-dimensional structure of graphene, consisting of an isotropic hexagonal lattice of carbon atoms, shows fascinating electronic properties, such as a gapless energy band and Dirac fermion behavior of electrons at fermi surface. Anisotropy can be induced in this structure by electrochemical pressure. In this article, by using tight-binding method, we review anisotropy effects in the elect...

The use of single molecules as active components in electronic devices is presently considered a potential alternative to semiconductor-based nanoscale electronics since it directly provides precisely-defined nano-scale components for electronic devices which eventually allows for simple processing and device fabrication. In the present thesis the self-assembly and electron transport properties...

A so called all-carbon based graphene field effect transistor (GFET) in which the electrodes are composed of graphite-like nano-sheets instead of metals in the traditional devices is fabricated by one-step e-beam direct writing (EBDW). It is also found that the graphite-like nano-sheets in electrodes are perpendicular to the channel graphene, which is confirmed by the transmission electron micr...

The SDS, PEG and CTAB roofed MgO nano powders were synthesized by co-precipitation method.  The sintered nano powders was shown Fm-3m space group with cubic phase obtained by the XRD pattern. The lattice strain was calculated to be used Williamson-Hall equations (W-H). The formation of Mg-O bond and hydroxyl radicals on the surface were confirmed by the FTIR analyses. The TEM revealed that the ...
