Single Wall Carbon Nanotube-Based Structural Health Monitoring Sensing Materials

Watkins A.N., Ingram J.L., Jordan J.D., Wincheski R.A., Smits J.M., Williams P.A., NASA Langley Research Center, US

Single-wall carbon nanotube (SWCNT)-based materials represent the future aerospace vehicle construction material of choice based primarily on predicted strength-to-weight advantages and inherent multifunctionality. As such, it is prudent to pursue the development of SWCNT-based sensing [...]

Scanning Probe Lithography on InAs Substrate

Houlet L.F., Yamaguchi H., Hirayama Y., NTT Basic Research Laboratories, NTT Corporation, JP

In this study, we focus our interest on patterning a conventional electron beam resist by electron field emission exposure using Atomic Force Microscope (AFM). We have fabricated 50-140 nm deep structures in InAs with the [...]

A New Wet Chemical Approach to the Selective Synthesis of Silver Nanowires

Hernandez E.A., Posada B., Irizarry R., Castro M.E., The University of Puerto Rico, US

A new wet chemical approach is presented for the selective synthesis of silver nanowires based on the assembly of silver nanoparticles covered with a bi-functional thiol. The particles are formed spontaneously upon the addition of [...]

Thermal Noise Response Based Static Non-Contact Atomic Force Microscopy

Gannepalli A., Sebastian A., Salapaka M.V., Cleveland J., Iowa State University, US

Micro-cantilever based devices have revolutionized imaging and they are the primary tools for investigation and control of matter at the nanoscale. In this paper a novel approach based on the thermal noise response of the [...]

Metal-Insulator-Metal Ensemble (MIME) Chemical Detectors

Smardzewski R.R., Jarvis N.L., Snow A.W., Wohltjen H., Mackay R.A., Edgewood Chemical Biological Center, U.S. Army SBCCOM, US

A new class of nanometer-scale, low power, solid-state devices is being investigated for the detection of hazardous vapors. These chemical vapor sensors are comprised of nanometer-sized gold particles encapsulated by monomolecular layers of alkanethiol surfactant [...]

Silicon Nanostructures Patterned on SOI by AFM Lithography

Ionica I., Montès L., Ferraton S., Zimmermann J., Bouchiat V., Saminadayar L., IMEP-INPGrenoble, GF

The actual trends in microelectronics are the reduction of the dimensions and the search of new devices standing upon new phenomena as in the case of a Single Electron Transistor (SET) that is based on [...]

On the Design of SET Adders

Sulieman M., Beiu V., Washington State University, US

Single-Electron-Technology (SET) is one of the future technologies distinguished by its small and low power devices. Among others, SET provides simple and elegant solutions for implementing threshold logic gates (TLG).One of the SET-TLG logic circuits [...]

In Situ Transformations of Gold Contacts Studied by Moleculad Dynamics Simulations

Pokropivny A.V., Pokropivny V.V., Lõhmus A., Lõhmus R., Lõhmus A., Lõhmus R., Erts D., Pokropivny A.V., Pokropivny V.V., Olin H., University of Latvia, EE

We apply molecular dynamics methods for simulation of in situ processes in new combined TEM/SPM technique. The atomic structure transformations of a gold nanobridge between two contacts are studied in processes of loading-unloading and friction [...]

Development of the Nano Aligner for CNT-tip fabrication

Kang G-S, Lee J.S., Choi J-S, Kwak Y-K, Kim S-H, KAIST, KR

AFM tip has been used for surface profiling with a fine resolution, but there is a barrier to improve its performance because of the low aspect ratio. Many researchers have solved this problem with attaching [...]

Nano Gripper using Carbon Nanotube

Lee J.S., Kwon S-K, Choi J-S, Kang G-S, Kwak Y-K, Kim S-H, KAIST, KR

In this paper, we proposed a nano gripper that was made from two nano probes. And, those nano probes were made from the tungsten tip and multi-wall carbon nanotube with acrylic adhesive under optical microscope. [...]

Displacement Detection using Quantum Mechanical Electron Tunneling in Micro and Nano-electro-mechanical Systems

Taylor D., Ekinci K., Boston University, US

Micro-electro-mechanical systems (MEMS) and, more recently, nanoelectromechanical systems (NEMS) are emerging as candidates for a number of important technological applications — such as ultra-fast actuators, sensors, and high frequency signal processing components. Experimentally, they are [...]

A Nanoscale Electromechanical Contact Switch for Logic Applications

Huang C-C, Ekinci K.L., Boston University, US

Here, we describe the operation of a nano-electro-mechanical contact switch. The switch design relies on a sharp contact tip integrated to a compliant nanomechanical beam. When the beam is actuated electrostatically, the tip establishes intimate [...]

Defects and Fault Characterization in Quantum Cellular Automata

Baradaran Tahoori M., Momenzadeh M., Huang J., Lombardi F., Northeastern University, US

In this paper, a detailed simulation-based characterization of QCA defects and study of their effects at logic-level are presented. Different defect mechanisms for QCA active devices and interconnects are considered and the appropriate fault models [...]

Investigation of Robust Fully-Silicided NMOSFETs for Sub-100 nm ESD Protection Circuits Design

Lee J.W., Tang H., Li Y., Natl Nano Device Labs & Natl Chiao Tung Univ, TW

Electrostatic discharge (ESD) becomes an important issue in vary large scaled integrated (VLSI) circuit design and manufacture, especially for the ultra-thin oxide nano-devices [1-3]. It results from a fact that the gate oxide will be [...]
