Whilst resonant transmission is well understood and can be fully harnessed for crystalline superlattices, a complete picture has not yet emerged for disordered superlattices. It has proven difficult to tune resonant transmission in disordered diamond-like carbon (DLC) superlattices as conventional models are not equipped to incorporate significant structural disorder. In this work, we present c...

Direct learning control (DLC) schemes have been developed recently to address non-repeatable trajectory tracking problems. Unlike conventional iterative learning schemes, DLC schemes learn a set of unknown basis function vectors which can be used to generate the desired control profile of a new trajectory. DLC schemes use all available trajectory tracking information to obtain the unknown basis...

As a candidate for the next generation lithography technology, nanoimprint lithography (NIL) has demonstrated its strong potential to fabricate high resolution (sub-10 nm) patterns with high throughput and low cost. One of its challenges for the acceptance of the industry is related to the mold life time that significantly affects cost of ownership and manufacturing reproducibility. Nowadays, m...

The telecommunications infrastructure has undergone a great deal of change recently, and it seems that the rate of change increases exponentially as time passes. For example, DLC technology and the local loop will become more important in the future in delivering the new services that customers will require. This tutorial first addresses the history of subscriber carriers because it is importan...

The mechanical and tribological properties of three types diamond like carbon (DLC) coatings, i.e., non-doped, Si-doped, W-doped DLC, are evaluated. Dry reciprocating sliding wear tests were performed to evaluate the effect frequency/velocity on friction, adhesion, wear. degree graphitization non-doped DLC increases with velocity, which results in a lower coefficient friction (COF), decrease ra...

The present paper describes the tribological properties of a mesh-like nanostructure diamond-like carbon (DLC) in formulated engine oil at DLC/steel contacts. This novel nanostructured DLC was characterized as non-hydrogenated amorphous (a-C) with nano-mesh structure layer outermost surface, herein named NM-a-C. From results our friction tests, we observed that NM-a-C/steel tribopair exhibited ...

A thin diamond-like carbon (DLC) film was deposited onto a densely packed "forest" of vertically aligned multiwalled carbon nanotubes (VACNT). DLC deposition caused the tips of the CNTs to clump together to form a microstructured surface. Field-emission tests of this new composite material show the typical low threshold voltages for carbon nanotube structures (2 V μm(-1)) but with greatly incre...

This study analyses the achievable cooperative diversity order of the distributed linear convolutional space-time coding (DLC-STC) scheme for time–frequency asynchronous cooperative networks. The authors first prove that perfect time or frequency synchronisation is impractical for cooperative networks with multiple relays serving multiple destinations even when the relays know all accurate time...

Secondary ion mass spectrometry (SIMS) data from diamond like carbon (DLC) often give inaccurate, imprecise results when methods tailored for silicon are applied. This work is a guide to accurate and precise future SIMS analyses of DLC.
