Electronic structure modulation of nickel hydroxide porous nanowire
The smooth surface of the NiMn-BTC nanowire is visible in the TEM image (Fig. S3d), and the overall needle-like nanowire array morphology is preserved (Fig. 2b-d). Notably, the enlarged image of Mn-Ni(OH) 2 PNAs ( Fig. 2 d) shows that the surface of nanowires became rather rough, which can increase the specific surface area, thereby faciliating

Apr 14, 2006Transport is governed by a metal-semiconductor Schottky barrier for the PZ ZnO NW (see movies S1 and S2). (A) Schematic definition of a NW and the coordination system. (B) Longitudinal strain ϵ z distribution in the NW after being deflected by an AFM tip from the side. The data were simulated by FEMLAB for a ZnO NW of length 1 μmand an aspect
JFET - Wikipedia
JFET operation can be compared to that of a garden hose flow of water through a hose can be controlled by squeezing it to reduce the cross section and the flow of electric charge through a JFET is controlled by constricting the current-carrying channel. The current also depends on the electric field between source and drain (analogous to the difference in pressure on either end

Nov 16, 2011Figure 6a shows a schematic cross-section of such an InAs–Si heterostructure nanowire device in which the tunnel junction is located between the n-type InAs nanowire and the p-type Si substrate.
Interfacial thermal resistance: Past, present, and future
Apr 22, 2022As devices and circuits scale to ever smaller sizes and thermal management in them becomes more important, heat transport across their interfaces plays a crucial role in their development. While the study of interfacial thermal resistance goes back almost 90 years, its increasing importance has led to significant recent progress in theory, experiment, and
Optical spectrometer - Wikipedia
An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the light's intensity but could also, for instance, be the polarization state.

Silicon Anode - an overview | ScienceDirect Topics
Krzysztof Jan Siczek, in Next-Generation Batteries with Sulfur Cathodes, 2019. 8.4 Silicon Anode. Silicon is a promising alternative to lithium as an anode for Li-S batteries, due to the high theoretical capacity of ~ 3580 mAh g − 1 (Li 15 Si 4) is known, the practical application of Si-based anodes is limited by a serious loss of capacity, which is attributed to mechanical
