Size dependent etching of nanodiamond seeds in the early stages of CVD diamond growth
R. Salerno, B. Pede, M. Mastellone +7
We present an experimental study on the etching of detonation nanodiamond (DND) seeds during typical microwave chemical vapor deposition (MWCVD) conditions leading to ultra-thin di…
Impact of seed density on continuous ultrathin nanodiamond film formation: an analytical approach
Massimo Tomellini, Riccardo Polini
An analytical mean field approach for describing the time evolution of film growth by seeding has been developed. The modeling deals with the generic case of anisotropic growth wit…
Interface evolution in phase transformation ruled by nucleation and growth
Massimo Tomellini
An analytical model for the evolution of the boundary of the new phase in transformations ruled by nucleation and growth is presented. Both homogeneous and heterogeneous nucleation…
Vibrational temperature of the adlayer in "hot atom" reaction mechanism
Massimo Tomellini
Hot-atoms reactions mechanisms bring about reaction rates which are several orders of magnitude higher than those expected in the case of ad-atoms which have thermalized with the s…
Beyond the constraints underlying Kolmogorov-Johnson-Mehl-Avrami theory related to the growth laws
M. Tomellini, M. Fanfoni
The theory of Kolmogorov-Johnson-Mehl-Avrami (KJMA) for phase transition kinetics is subjected to severe limitations concerning the functional form of the growth law. This paper is…
Eliminating overgrowth effects in Poisson spatial process through the correlation among actual nuclei
M. Tomellini, M. Fanfoni
It has been shown that the KJMA (Kolmogorov-Johnson-Mehl-Avrami) solution of phase transition kinetics can be set as a problem of correlated nucleation [Phys.Rev.B65, 172301 (2002)…
