We have investigated the effectiveness of a thin n-In0.2Ga0.8N layer inserted in the bottom n-GaN layer of InGaN/GaN blue light emitting diodes (LEDs) for the protection of multiple quantum wells during the laser lift-off process for vertical LED fabrication. The photoluminescence properties of the InGaN/GaN lateral LEDs are nearly identical irrespective of the existence of the n-In0.2Ga0.8N insertion layer in the bottom n-GaN layer. However, such an insertion is found to effectively increase the photoluminescence intensity of the multiple quantum well and the carrier lifetime of the vert

Due to the natural dislocations in the GaN epilayers and released stress after LLO process, the strong leakage current occurs. Besides, the ICP process would also cause the leakage current of sidewall. Although the leakage current would make the light intensity and efficiency of the LEDs decay, the light intensit

By deposition of the film on p-type GaN followed by thermal treatment in oxygen ambient at 550℃ for 5 minutes, we obtained good Ohmic characteristic with a specific contact resistivity as low as 1.1×10-4 Ω-cm2.

They met casually at public events in the 1980s when Clinton was in Washington lobbying on behalf of the nation’s governors, but for the most part they observed each other from a distance. “We had a distant awareness of each other,” recalled Gingrich, who remembered a brief encounter with Clinton during a national governor’s convention in 1988.

Pulsed eddy current (PEC) technique is attractive for detection of surface defects and wall-thinning in covered electrically conductive materials. This paper discusses development of PEC technique and two different types of self-nulling probes (differential Hall sensors and Double-D differential coils) for detection of surface notches in a thick stainless steel plate. PEC testing of covered objects is attempted. In this regard, the influence of lift-off on the PEC signal due to insulation shims and thin aluminum layer is studied using the peak amplitude and the performance of the two probes is

Abstract The effect of particle inertia on small particles diffusing in a turbulent wall bounded flow is calculated. The equation for a single particle is simplified assuming the particle response time is small compared to the time scale associated with turbulent fluctuations. Continuum equations are obtained from the single particle equation by consideration of mass and momentum conservation in a control volume by the use of volume averaging. Turbulent averaging is then carried out and the resulting correlations are modelled using results borrowed from second moment turbulence clo sure theory

Coherent Anti-Stokes Raman Scattering (CARS) has been particularly useful for making temperature measurements in flames. A majority of the CARS instruments is used in studies of small-scale burners, piston engines, and even furnaces and boilers of industrial size. Occasional investigations of species concentrations and rotational and vibrational temperatures in rarefied gases have also been conducted. In the area of aerospace research, one must tackle very delicate problems in all of these fields. For instance, it is particularly difficult to investigate cryogenic rocket motor combustion, hype
