Black phosphorus (BP) is the most stable allotrope of phosphorus which exhibits strong in-plane anisotropic charge transport. Discovering its interface properties between BP and high-k gate dielectric is fundamentally important for enhancing the carrier mobility and electrostatics control. Here, we investigate the impact of interface engineering on the transport properties of BP transistors wit...

Fluorine-treated titanium nitride-silicon oxide-hafnium oxide-silicon oxide-silicon devices (hereafter F-MOHOS) are candidates for total ionization dose (TID) radiation sensor applications. The main subject of the study reportedherein is the performance improvement in terms of TID radiation-induced charge generation effect and charge-retention reliability characterization for F-MOHOS devices. I...

Configuration-constrained nuclear shape calculations are used to show that reinforcing neutron and proton orbital structures create exceptional conditions for the formation of multiquasiparticle isomers in neutron-rich hafnium isotopes, with axially symmetric, prolate shapes. Highly excited, long-lived states are predicted. However, at angular momenta close to 40\ , orbital alignment effects fo...

HF radar systems are widely and routinely used for the measurement of ocean surface currents and waves. Analysis methods presently in use are based on the assumption of infinite water depth, and may therefore be inadequate close to shore where the radar echo is strongest. In this paper, we treat the situation when the radar echo is returned from ocean waves that interact with the ocean floor. S...

BACKGROUND There is a growing trend of inactivity among children, which may not only result in poorer physical health but also poorer cognitive health. The purpose of this study was to investigate the relationship between aerobic fitness and proactive and reactive cognitive control using a continuous performance task (CPT). METHODS Forty-eight 9- to 10-year-old children (n = 24 higher fit [HF...

Metal-assisted chemical etching (MaCE) of a (100) n-type GaP using patterned Pd catalysts in a mixed solution of HF and H2O2 at room temperature is reported for the first time. Various patterns of Pd catalysts, i.e., meshes and patches, with length scales ranging from 200 nm to several μm were used. Depending on the sizes of the Pd catalysts, GaP exhibits two distinctively different MaCE mechan...
