Nonlinear Response in Nanoshear Modulation Force Microscopy: Fourier Analysis

Haugstad G., University of Minnesota, US

Oscillatory methods in scanning probe microscopy have enabled nanoscale tribology and rheology investigations on polymeric systems. Among these methods, shear modulation force microscopy has been used to probe phenomena such as the stick-to-slide transition, time-delayed [...]

Quantification of Properties for Ferroelectric Thin Films Using Piezo-response Force Microscopy

Cain M.G., Lowe M.J., Cuenat A., Stewart M., Blackburn J., National Physical Laboratory, UK

Ferroelectric thin films are used within FE-RAM Memory devices, thermal imaging cameras and for new and emerging micro-integrated applications. Piezo Force Microscopy (PFM) is a method that can be used to probe (using a modified [...]

Visualizing Nano-Electromechanics by Vector Piezoresponse Force Microscopy

Rodriguez B.J., Jesse S., Baddorf A.P., Kalinin S.V., Gruverman A., Oak Ridge National Laboratory, US

This is a detailed examination of the electro-mechanical and elastic coupling that occurs in the scanning probe microscopy of electro-active materials. This research is useful to detecting, imaging and understanding the orientation of nanoscale electromechanical [...]

Mechanical Nonlinear Generation with Coupled Torsional Harmonic Cantilevers for Sensitive and Quantitative Atomic Force Microscopy Imaging of Material Characteristics

Sahin O., Quate C.F., Solgaard O., Stanford University, US

Tapping-mode atomic force microscopy has been the most widely used mode of operation. Due to non-linear tip-sample forces, dynamics of the cantilever motion is an extremely rich problem. Recent studies have shown that higher harmonics [...]

Growth of Si Nanowires on Nano Catalyst Corners

Wang C., Malladi K., Madou M., University of California Irvine, US

One dimensional structure with nanometer diameters, such as Si nanowires, have great potential for understanding and testing fundamental concepts about the roles of dimensionality in optical, electrical and mechanical properties and for applications ranging from [...]

Conductivity of the Crystalline Boron Nanowires Measured in TEM

Lourie O., Gatan Inc., US

In this experiment we report on using in-situ STM-TEM system and EELS to characterize the electronic properties of the boron nanowires. We use low loss EELS approach to study the band structure and the dielectric [...]

Acid Transformation of TiO2 Nanotubes to Nanoparticles

Bavykin D.V., Lapkin A.A., Friedrich J.M., Walsh F.C., University of Bath, UK

Transformation of TiO2 nanotubes in the presence of sulfuric acid to TiO2 nanoparticles was studied. The possible physico - chemical reasons for such transformations are critically discussed.

Growth of 3C-SiC Nanowires on Nickel Coated Si(100) Substrate using Dichloromethylvinylsilane and Diethylmethylsilane by MOCVD Method

Kang B.-C., Hyun J.S., Boo J.-H., Sungkyunkwan University, KR

3C-SiC nanowires have been deposited on nickel coated Si(100) substrates using single source precursors by thermal metal-organic chemical vapor deposition (MOCVD) method. Dichloromethylvinylsilane (CH2CHSiC(CH3)Cl2) and diethylmethylsilane (CH3 SiH(C2H5)2) were used as a single precursor without [...]

First-Principles Studies of SnS2 Nanotubes

Chang H., In E., Kong K-J, Lee J-O, Choi Y., Ryu B-H, Korea Research Institute of Chemical Technology, KR

First principles calculations are used to predict the stability and electronic structures of SnS2 nanotubes. Optimization of several structures and their corresponding strain energies confirms the stability of SnS2 nanotube structures. Band structure calculations show [...]
