An atomic-scale thickness, molecular impermeability, low atomic number, and mechanical strength make graphene an ideal electron transparent membrane for scanning electron microscopy and spectroscopy in liquids. Here, we present a novel sample platform made

International comparisons between National Metrology Institutes (NMIs) are important to verify measurement results and the associated uncertainties. In this paper, we report a comparison of the line width calibration of a crystal silicon line width

Improving the power conversion efficiency of photovoltaic (PV) devices is challenging because the generation, separation and collection of electron-hole pairs in PV devices is strongly dependent on details of the nanoscale chemical composition and defects
The 2017 International Conference on Frontiers of Characterization and Metrology for Nanoelectronics (FCMN) has the goal of bringing together scientists and engineers interested in all aspects of the characterization and measurement technology needed for

In many fields of research and production, a great deal of dimensional metrology, characterization and process control is accomplished using scanning electron microscopes (SEM). The accuracy of these SEM measurements has always been important, but is often

Photothermal induced resonance (PTIR) is a method for optical spectroscopy that allows for infrared chemical imaging at spatial resolution below the limit of diffraction. By using the mechanical resonance of the cantilever for amplification the technique

We present a new method for two-port vector-network-analyzer calibration which uses multiple offset-reflect standards and a flush thru connection. Offset-reflect standards consist of sections of the same uniform transmission-line with different lengths
Reference materials are essential tools to assure the quality of measurement results, from R&D labs to production facilities. They help increase the reliability of measurements, as laboratories can use reference materials to verify, for themselves, and

The exciting commercial application potential of graphene materials may inevitably lead to their increasing environmental exposure and risk. This study focused on using carbon-14 labeled few-layer graphene (FLG) to determine whether the size of graphene
Recent advances in instrumentation for Secondary Ion Mass Spectrometry (SIMS) have focused on the application of polyatomic primary ions for enhancing molecular secondary ion signals of organic materials. A few studies have also noted that some polymers

Abstract Three-dimensionally (3D) structured photoelectrodes offer a number of potential benefits for solar fuels production compared to conventional planar photoelectrodes, including decreased optical losses, higher surface area for catalysis, more facile
A methodology to reconstruct a distributed force applied to an atomic force microscopy (AFM) cantilever given the shape in which it vibrates is developed. This is accomplished by rewriting Bernoulli Euler beam theory such that the force on the cantilever

Carbon nanotubes (CNTs) are increasingly used in consumer and structural polymeric products to enhance a variety of properties. Under weathering, the polymer matrix will degrade and the nanofillers will potentially be released from the products, which
We use flat-histogram Monte Carlo simulations to study how changing the flexibility of soft porous crystals (SPCs) affects their selective adsorption of a binary, size-asymmetric supercritical fluid. Specifically, we consider mesoporous SPCs which have
As the production of carbon nanotubes (CNTs) expands, so does the potential for release into the environment. The possibility of bioaccumulation and toxicological effects has prompted research on their fate and potential ecological effects. For many

We demonstrate an open-loop self-excitation response in a curved, bistable microelectromechanical beam under a time-independent electrostatic load. The self-excitation is triggered by placing a high value resistor in series with a beam that is on the verge
Sorting of single-wall carbon nanotubes by their electronic and atomic structures in liquid phases is reviewed in this chapter. We first introduce the sorting problem, then provide an overview of several sorting methodologies, following roughly the
The integration of graphene into nanoscale electrical and mechanical devices is often limited by the ability to grow monolayer graphene on extremely thin copper films (
Microwave magnetodynamics in ferromagnets are often studied in the limit of small-amplitude modes that modulate a well-defined magnetic state. However, strongly nonlinear regimes, where the aforementioned limits are not applicable, have become

While graphene has substantial commercial potential, numerous aspects regarding its potential ecological effects such as its potential for bioaccumulation are not well known. 14C-labeled few layer graphene (FLG) was spiked to artificial freshwater and the

Understanding how the electronic band structure of a ferromagnetic material is modified during laser-induced demagnetization on femtosecond timescales has been a long-standing question in condensed matter physics. Here, we use ultrafast high harmonics to

Laser-assisted atom probe tomography (L-APT) was used to examine superconducting TiN/Ti/TiN trilayer films with nominal respective thicknesses of 5/5/5 (nm). The trilayers were deposited on Si substrates by reactive sputtering. Electron energy loss

We present the application of our newly developed multi-reflect-thru technique to vector-network-analyzer calibration in the on-wafer environment. This technique uses a set of highly-reflective one-port devices, referred to as offset-reflects, and a single
