Charged clusters in thin film growth
Nong-Moon Hwang,Doh-Yeon Kim +1 more
Abstract: A cauliflower structure is a granular film composed of spherical particles similar in size, each with numerous nanoscale nodules on its surface. The structure is produced during certain chemical vapour deposition (CVD) processes for diamond and silicon thin film growth. A classical account in terms of atomic unit deposition fails to explain the growth of such a cauliflower structure, as it requires a gas phase of much higher supersaturation than for onset of diffusion controlled growth. Another interesting and somewhat puzzling phenomenon encountered during a diamond CVD process is that while diamond is depositing on a graphite substrate, carbon atoms in the graphite itself are etched away into the vapour phase; that is, experience evaporation. Again, an elementary kinetic barrier mechanism fails to explain such CVD deposition of a less stable diamond phase combined with simultaneous evaporation of a stable graphite phase. In order to account for such puzzling CVD phenomena and others, a theory o...

Effect of methane concentration on size of charged clusters in the hot filament diamond CVD process
TL;DR: In this article, negative charged clusters of 3000-18000 atomic mass units were experimentally confirmed under typical process conditions of hot-filament diamond CVD using gas mixtures of 1-5% CH4 and H2.

Scale control by threshold treatment
TL;DR: In this paper, a threshold treatment process is used for the control of scale in sea water evaporators, and the search for improved additives is made difficult by the lack of understanding of the mechanism of the process.

TL;DR: In this article, it has been established that the incidence of twinning is associated with a condition of high supersaturation in the nutrient solution and is frequently accompanied by spontaneous microcrystallization.
