Abstract

A. M. Zaitsev and I. A. Dobrinets: Carbon nanodots made on diamond surface by focused ion beam

Continuum theory of carbon phases

“…The above presented conjecture allows us to interpret results of the experiments on FIB irradiation of the surface of the single crystal CVD diamond film [18][19][20]. Ga þ -ion-beam scanning irradiation of the films produced nanodots and nanowires of the width approximately equal to the diameter of the beam that is $ 20 nm [18][19][20].…”

“…surfaces with non-carbon ions [18][19][20], etc. Regardless of the preparation technique na-C's have two common features.…”

“…In Section 3 we apply the developed model to the problem of crystallization of graphite by considering the processes of nucleation of graphite from liquid phase. The model will be also used in the present paper to gain an insight into the equilibrium properties of the amorphous phase of carbon at nanoscale dimensions (na-C) and amorphization of carbon under conditions of FIB irradiation of CVD-diamond nanofilms [18][19][20]. In Section 4 we discuss the obtained results and extensions of the model on different systems.…”

“…Ga þ -ion-beam scanning irradiation of the films produced nanodots and nanowires of the width approximately equal to the diameter of the beam that is $ 20 nm [18][19][20]. The nanostructures were stable at the room temperature; their conductivity was smaller than that of the graphite but greater than that of the diamond.…”

On the way to mass-scale production of perfect bulk diamonds

“…In conclusion, I would like to mention one more important advantage of LPHT annealing-the opportunity for controllable high-temperature treatment of diamond surfaces, which is of crucial importance for the micro-and nanostructuring of diamonds (14,15). For example, Fig.…”
