Large size and low dislocation density bulk gallium nitride (GaN) crystals were successfully grown by original acidic ammonothermal method SCAAT™ (Super Critical Acidic Ammonia Technology). It enabled us to obtain extremely high crystallinity true

The effect of the thermal annealing on an acidic ammonothermal gallium nitride (GaN) crystal grown toward the c- and m-directions was investigated. The specific annihilation of hydrogenated Ga vacancies was confirmed for the GaN crystal grown toward

An evident issue in performing GaN growth along the c-direction is the generation of V-shaped pits on its surface. Here, we investigated the transition of the angle of facets forming a V-shaped pit via three-photon excitation photoluminescence (3PPL)

Molecular dynamics simulations with the Langevin equation using a coarse-grained, bead-spring model were performed to investigate the dynamic properties of nanoscale lubricant films. The simulated spreading profiles of lubricant nanofilms are in qual

Viscoelastic characteristics including the viscosity, storage modulus, and loss modulus of perfluoropolyether (PFPE) lubricants with reactive endgroups are examined via a rotational rheometer. Both temperature and molecular weight effects on rheologi

In this paper, we present rigorous simulation tools: a lattice-based simple reactive sphere model, an off-lattice bead-spring Monte Carlo model, and a molecular dynamics model. These tools accurately describe the static and dynamic behaviors of perfl

An off-lattice Monte Carlo simulation using a coarse-grained bead-spring model was developed to analyze nanoconfined polymer films. The beads in the polymer chains are connected via finitely extensible, nonlinear elastic springs. In addition to nonpo

The thermodynamic stability of ultra-thin perfluoropolyether (PFPE) films is examined. The model used in this paper incorporates a layered structure due to polar interaction at the endgroups and provides the stability criteria as a function of film t
