Template‐Confined Synthesis of Shape‐Engineered Single‐Crystal Gold Microplates in Lithographically‐Defined Polymeric Patterns

Advanced Functional Materials, EarlyView.
Single‐crystal gold microplates are high‐performance nanomaterials with an impressive wafer‐based application space. Progress has, however, been tempered by an inability to exert synthetic control over microplate size, shape, and positioning. In this work, control over these parameters is demonstrated using a seed‐mediated synthesis that both confines ...

Barrier height distributions – the influence of weak channels

EPJ Web of Conferences, 2011
The barrier distributions for the 20Ne+58,60,61Ni systems were experimentally determined. In the 58Ni case one observes a distinct “structure” in the distribution (two peaks) which is partially damped for 60Ni and completely smoothed out for 61Ni.

Barrier Height at the Graphene and Carbon Nanotube Junction

, 2018
—Graphene/carbon nanotube (CNT) junction barrier height was investigated using all-carbon field-effect transistor structure with graphene and single-walled CNT (SWCNT) network as source (S)/drain (D)/gate electrodes and as channel, respectively.

Adhesive energy, force and barrier height between simple metal surfaces [PDF]

, 1992
Using the self-consistent field pseudopotential method we calculated the adhesive energy, perpendicular and lateral forces and barrier height between two rigid A1(001) slabs modeling the sample and a blunt tip.

A Holistic Stabilization of the Anode in Lithium‐Sulfur Batteries Through a Ternary Alloy Fusion

Advanced Functional Materials, EarlyView.
LiTeAl anodes fabricated through a scalable thermal fusion technique holistically addresses the stability issues faced by lithium‐metal anodes in lithium–sulfur batteries. Aluminum forming a skeletal network with lithium suppresses dendrite growth and enhances energy density, while tellurium forming a robust SEI facilitates Li+‐ion flow.

Phase Evolution Kinetics in Additive‐Free 19.75% Organic Photovoltaics Empowered by Solvent Vapor Annealing

Advanced Functional Materials, EarlyView.
Solvent vapor annealing enables kinetic control of additive‐free morphology in organic solar cells. Selective plasticization of acceptor forms an optimal fibrillar network, boosting efficiency to 19.06% (binary) and 19.75% (ternary), with ultrafast exciton dissociation and reduced recombination.

Temperature dependence of barrier height in a Ni/β-Ga2O3 Schottky barrier diode precisely determined by the analysis based on the thermionic emission-diffusion model

Applied Physics Express
Temperature dependence of the barrier height in a Ni/ β -Ga _2 O _3 Schottky barrier diode has been investigated in 303–573 K. The barrier height obtained by the capacitance–voltage ( C – V ) measurements slightly decreased with increasing temperature ...

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Barrier height inhomogeneity in electrical transport characteristics of InGaN/GaN heterostructure interfaces

AIP Advances, 2015
We have grown InGaN/GaN heterostructures using plasma-assisted molecular beam epitaxy and studied the temperature dependent electrical transport characteristics. The barrier height (φb) and the ideally factor (η) estimated using thermionic emission model
