In this paper, a simple lattice model of the metal-organic adsorption layer of 1,3,5- tris(pyridyl)benzene and copper on the surface of Ti2CO2 was proposed. In this model, the selfassembly of the organometallic layer is considered as a one-component system that implicitly includes metal adatoms. The ground state phase diagram is calculated. A Monte Carlo simulation is performed using the Metropolis algorithm and the parallel temperature technique. The isotherm of the metal-organic is calculated at T = 300 K. All the results indicate the possibility of the formation of stable metal-organic phases on the Ti2CO2 surface.

AbstractWe demonstrate photoluminescence from self- assembling InGaN quantum dots (QDs), which are artificially fabricated on AlGaN surfaces via metal- organic chemical vapor deposition. InGaN QDs are successfully fabricated by the growth mode transition from step- flow to three dimensional island formation by using anti-surfactant silicon on AlGaN surface. The diameter and height of the fabricated InGaN QDs are estimated to be ˜10nm and ˜5nm, respectively, by an atomic- force- microscope (AFM). Indium mole fraction of InxGal−x N QDs is controlled from x=˜0.22 to ˜0.52 by varying the growth temperature of QDs. Intense photoluminescence is observed even at room temperature from InGaN QDs embedded with the GaN capping layers. In addition, the temperature- dependent energy shift of the photoluminescence peak- energy shows a localization behavior.
