In this work, the electron dispersive spectroscopy (EDS) methodology was used to identify the thin stack oxide-nitride oxide (ONO) structure of advanced NAND flash products. By the specific dual silicon drift detectors (SDDs) hardware design and the optimized parameters for data acquisition, the accurate results from a damage-free specimen can be obtained.
White light-emitting diodes (LEDs) with roughened-dispensing package through a simple imprinting technique are demonstrated and fabricated. The imprinting mold was fabricated by naturally wet-etched (100) Si substrate, which did not require expensive lens mold and pattern definition. The lumen output of roughened-dispensing package was enhanced by 5.4 % and 2.5 %, at driving current of 120 mA, compared...
A single-junction InGaP solar cell with polystyrene (PS) nanospheres on the surface has been developed. The self-assembly of PS nanospheres is one of the simplest and the fastest methods with which to build a 2-D closely packed periodic structure. Due to the scattering of the PS nanospheres, the light path length can be increased when compared to the InGaP solar cells without PS nanospheres on the...
The semi-polar InGaN-based LEDs exhibits low efficiency droop because the reduction of the polarization field not only made the band diagram smoother but also restricted electron overflow to the p-GaN layer as shown in simulations.
This paper systematically studies and demonstrates how to lower the operating voltage for an electrowetting optical beam refractor (EOBR). The results indicate that a low operating voltage can be achieved by decreasing the thickness of the dielectric layer and employing a higher dielectric constant, together with reducing the interfacial surface tension between the electrolyte and the surrounding...
