Ga^+ beam lithography for nanoscale silicon reactive ion etching [PDF]

, 2010
By using a dry etch chemistry which relies on the highly preferential etching of silicon, over that of gallium (Ga), we show resist-free fabrication of precision, high aspect ratio nanostructures and microstructures in silicon using a focused ion beam ...

Advances in Deep Silicon Etch Processing Using Bosch Process

Journal of the Vacuum Society of Japan, 2010
Deep Reactive Ion Etching1-3) is well established as a commercial technique for forming Micro-Electro-Mechanical Systems (MEMS) devices. Over the last decade, development work has led to increases in silicon etch rate of an order of magnitude while requirements for etch depth uniformity and profile control have become more stringent as the wafer size ...

Role of solvent-anion charge transfer in oxidative degradation of battery electrolytes

Nature Communications, 2019
Based on computations, the authors show that voltage stability of battery electrolytes is determined not by a single component but by formation of charge transfer complexes between salt anions and solvent molecules.

Hybrid Heterostructures of Nanostructured Si Membrane and MoS2 for Self‐Powered Photodetectors

Advanced Electronic Materials, EarlyView.
A scalable MoS2/Si nanomesh vertical heterostructure is developed for self‐powered photodetection. The nanostructured junction enhances conductivity, expands the active heterointerface, and enables a transition from photovoltaic to avalanche‐assisted operation, delivering markedly improved photoresponse over planar counterparts.

Food Prices and Inflation Expectations in New Zealand

Agribusiness, EarlyView.
ABSTRACT Food prices are conspicuous, and spending on food constitutes a considerable share of household expenditure. In this study, we use partially identified Bayesian structural vector autoregression models to analyze the effects of food price shocks on core inflation and 1‐ and 5‐year inflation expectations in New Zealand.

A nationwide assessment of hepatocellular adenoma resection: Indications and pathological discordance

Hepatology Communications, EarlyView., 2022
Abstract Hepatocellular adenomas (HCAs) are benign liver tumors associated with bleeding or malignant transformation. Data on the indication for surgery are scarce. We analyzed indications and outcome of patients operated for HCAs < 50 mm compared to HCAs ≥ 50 mm. Changes in final postoperative diagnosis were assessed.
