In a recent special issue of Chemical Vapor Deposition devoted to nanodiamonds, editors Amanda Barnard and Oliver Williams note that "the diversity of nanocarbon structures and allotropes has led to a plethora of growth techniques and unique properties, and has opened the door to a number of exciting applications."
An invited review article by Anirudha V. Sumant (CNM) and James Butler (Naval Research Laboratory) shows how nanocrystalline diamond is a designer material that can be tailored to speciﬁc applications. Materials that grow by using a suppression of renucleation, similar to conventional diamond growth, are distinguished from materials grown by using intentional enhancement of renucleation processes.
These specially designed nanodiamond materials find use in X-ray windows and lithography, micro- and nanomechanical and optical resonators, tribological shaft seals and AFM probes, electron field emitters, platforms for chemical and DNA sensing, to name a few applications.
The CNM offers a Lamda Technologies microwave plasma chemical vapor deposition system in its user program for the growth of ultrananocrystalline diamond films.
