Phosphorene, also known as monolayer black phosphorous, has been widely used in electronic devices due to its superior electrical properties. However, its relatively low Young's modulus, low fracture strength and susceptibility to structural failure has limited its application in nano devices. Therefore, in order to design more mechanically reliable devices that utilize phosphorene, it is neces...

Some issues such as tunneling, leakage current and light atom penetration through the film are threatening the ultra thin SiO2 be as a good dielectric for future industrial and electronic devices. Moreover, ultra fine and pure ZrO2/CrO2 are also so important in ceramic technologies. We have demonstrated a series of experiments to synthesis ZrO2 as well as CrO2 at low temperature with using sol-...

Carbon-based materials such as carbon nanotubes (CNTs) and Graphene nano-ribbons (GNRs) have been extensively studied in recent years due to their exceptional electronic, opto-electronic, and mechanical properties. We employed the non-equilibrium Green’s function (NEGF) formalism to analyze the electronic and optoelectronic properties of CNTand GNRbased devices numerically. The steady-state and...

in this paper, zno thin film is deposited on slide glass substrate using the sol-gel process. presenting well-defined orientation of zno thin films nanostructure were obtained by dip coating of zinc acetate dihydrate, monoethanolamine (mea), de-ionized water and isopropanol alcohol. the annealed zno thin films were transparent ca 85-90% in visible range with an absorption edges at about 375 nm....

Need for increased accuracy and precision in nano/micro movements and other devices (e.g. electronic, microscopy, medical etc.) has led to the development of allied technologies. The performance of these precision devices depends heavily upon accurate micro positioning of various links and joints. This has led to development of associated micro/nano mechanisms. Development of Microfactories nee...

Recently, in the development for piezoelectric and ferroelectric devices, the characterization method for nano-scale structure such as a ferroelectric domain and ferroelectric domain boundary (FeDB) has been important. The ultrasonic atomic force microscopy (UAFM) is expected to have the potential of elasticity characterization on the ferroelectric domain with nano-scale spatial resolution. In ...

The integration of nano structures with opto-electronic devices has many potential applications. It allows the coupling of more light into or out of the device while decreasing the size of the device itself. Such devices are reported in the VIS and NIR regions. However, making plasmonic structures for the UV region is still a challenge. Here, we report on a UV nano-antenna integrated metal semi...

The anodization of aluminum is an electro-chemical process that changes the surface chemistry of the metal, via oxidation, to produce an anodic oxide layer. During this process a self organized, highly ordered array of cylindrical shaped pores can be produced with controllable pore diameters, periodicity and density distribution. This enables anodic aluminum oxide (AAO) membranes to be used as ...

Our inability to accurately monitor individual neurons and their synaptic activity precludes fundamental understanding of brain function under normal and various pathological conditions. However, recent breakthroughs in micro- and nano-scale fabrication processes have advanced the development of neuro-electronic hybrid technology. Among such devices are three-dimensional and planar electrodes, ...

Patterning of materials at sub-10 nm dimensions is at the forefront of nanotechnology and employs techniques of various complexity, efficiency, areal scale, and cost. Colloid-based patterning is known to be capable of producing individual sub-10 nm objects. However, ordered, large-area nano-arrays, fully integrated into photonic or electronic devices have remained a challenging task. In this wo...
