Graphene films are grown by chemical vapour deposition on copper layer and then transferred onto a silicon substrate, coated with silicon dioxide. The topological characterization of the produced film is performed by atomic force microscopy, and the sheet resistance is measured by applying the four-probe test method. The equivalent single conductor model is then used in order to analyze the signal...
The areas of nanoscience and nanoengineering have been developing very fast; a large range of nanoscale materials has been studied in view of various practical applications. Much work is performed in the area of innovating coatings. Such films require specific properties such as proper conduction and mechanical ones. These properties can be studied by conductive probe AFM (CP-AFM) techniques. These...
Miniaturized thermoelectric coolers is one of the most promising active heat dissipating methods in hot spot cooling, laser cooling and other applications. Improving mechanical strength can potentially boost the reliability of this technology. In this paper, simulations and mechanical compression experiments were carried out on miniaturized thermoelectric coolers both with and without underfiller...
In this paper, multilayer graphene nanoribbon (GNR) is proposed as an emerging interconnect solution, which can be integrated with GNR devices to establish a monolithic GNR circuit. Both interconnect resistance and gate capacitance in this circuit are significantly reduced, leading to an RC delay improvement up to 60%. Since the interconnect performance determines the IC operations, this proposed...
We have demonstrated multi-walled carbon nanotube (MWCNTs) based sensors, which are capable of detecting alcohol vapor. The properties of the sensor were as a function of baking times at ethanol flow rate 200 cc/min and nitrogen gas flow rate 200 cc/min. Moreover, the various of baking times were observed that the highest sensitivity was obtained at baking time of 25 minutes at 70??C can be explained...
Undoped Nanostructured Titanium Dioxide thin film (UN) and Cobalt doped nanostructured (CoDN) TiO2 thin film has successfully prepared using sol-gel method and deposited onto silicon and glass substrate by spin coating technique. Nanostructured TiO2 thin film were prepared at 0.1 M, 0.2 M, 0.3 M and 0.4 M, Co doped TiO2 thin film was prepared with additional of ion Co at 1 at%. The electrical and...
Transconductance (gm) enhancement in n-type and p-type nanowire field-effect-transistors (nwFETs) is demonstrated by introducing controlled tensile strain into channel regions by pattern dependant oxidation (PADOX). Values of gm are enhanced relative to control devices by a factor of 1.5 in p-nwFETs and 3.0 in n-nwFETs. Strain distributions calculated by a three-dimensional molecular dynamics simulation...
Capacitive humidity sensors were fabricated using countersunk interdigitated electrodes coated with amorphous nanostructured TiO2, SiO2, and Al2O3 thin films grown by glancing angle deposition. The capacitive response and response times for each sensor were measured. The sensor utilizing TiO2 exhibited the largest change in capacitance, increasing exponentially from ~ 1 nF to ~ 1muF for an increase...
