Hide Abstract
In this Article, we report the successful fabrication of large-area ordered Si nanowire arrays (NWAs) by a cost-effective and scalable wet-etching process in combination with nanospheres lithography technique. The periodical Si NWAs are further investigated as photocathode for water splitting, with excellent hydrogen evolution performances with a maximum photocurrent density of 27 mA cm(-2) achieved, which is ?2.5 times that of planar Si and random Si nanowires electrode. The greatly improved PEC performance can be attributed to the patterned and ordered NWs structure as a result of enhancement of the light harvesting as well as charge transportation and collection efficiency.

Hide Abstract
Fabrication of semiconductor single and double quantum dot (QD) nanostructures is of utmost importance due to their promising applications in the study of advanced cavity quantum electrodynamics, quantum optics and solid-state spin qubits. We present results about the controllable growth of self-assembled single and double SiGe QD arrays with an ultra-low areal density of 1 × 10(7) cm(-2) on nanohole-patterned Si substrates via molecular beam epitaxy. The two dots in a double QD (DQD) aligned along the elongation direction of the nanoholes and show unsymmetrical features in both size and composition due to the asymmetric nanohole profiles after Si buffer layer growth. The interdot spacing between the two dots in a DQD could well be adjusted by changing the elongation ratio of nanoholes. Moreover, whether a single or a double QD formed in a given nanohole was found to be determined by the growth temperature of the Si buffer layer, the reason of which is given by the calculation of the surface chemical potential around the nanoholes after the buffer layer growth.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
