Nonclassical radiation from diamond nanocrystals
نویسندگان
چکیده
The quantum properties of the fluorescence light emitted by diamond nanocrystals containing a single nitrogen-vacancy (NV) colored center is investigated. We have observed photon antibunching with very low background light. This system is therefore a very good candidate for the production of single photon on demand. In addition, we have measured larger NV center lifetime in nanocrystals than in the bulk, in good agreement with a simple quantum electrodynamical model.

Diamond cubic Sn-rich nanocrystals: synthesis, microstructure and optical properties
Diamond cubic Sn-rich nanocrystals were fabricated with radii less than 20 nm by post-growth annealing at T = 750 ◦C of SnxGe1−x alloys grown on Ge(001) by molecular beam epitaxy. The crystal phase of the Sn-rich nanocrystals was determined to be diamond cubic from Fourier transform analysis of high-resolution transmission electron microscopy images. Optical transmittance of these SnxGe1−x/Ge (...
متن کاملSize tunable synthesis of solution processable diamond nanocrystals.
Diamond nanocrystals were synthesized catalyst-free from nanoporous carbon at high pressure and high temperature (HPHT). The synthesized nanocrystals have tunable diameters between 50 and 200 nm. The nanocrystals are dispersible in organic solvents such as acetone and are isotropic in nature as seen by dynamic light scattering.
متن کاملGeneration of Nonclassical States of the Radiation Field in the System of a Single Trapped Atom in a Cavity within the First Order of the Lamb-Dicke Approximation
In this paper, we propose a theoretical scheme for the generation of non-classical states of the cavity field in a system of a single trapped atom via controlling the Lamb-Dicke parameter. By exploiting the super-operator method, we obtain an analytical expression for the density operator of the system by which we examine the dynamical behaviors of the atomic population inversion, the phase-spa...
متن کاملGround states of group-IV nanostructures: Magic structures of diamond and silicon nanocrystals
We have developed an effective model to investigate the energetic stability of hydrogenated group-IV nanostructures, followed by validations from density-functional theory calculations. The Hamiltonian of XmHn (X = C, Si, Ge, and Sn) is expressed analytically by the atom numbers (m, n) and the magic numbers of diamond nanocrystals and silicon nanocrystals are determined. It is found that surfac...
متن کاملMagic-sized diamond nanocrystals.
The 2D structural transformation of a heavily boron-doped diamond surface has been revealed using scanning tunneling microscopy (STM). We found that at boron densities above the metal-insulator transition the diamond surface is comprised of spatially ordered magic-sized nanocrystals. The development of quantized electron gas inside these nanocrystals is directly confirmed by STM observation of ...
