We propose a platform to achieve ultra-high Quality factor (Q) optical resonators based on semiconductor nanowires. By defining one-dimensional photonic crystal at nanowire ends and engineering the micro-cavity pattern, cavities with Q of 3×10 5 and mode volume smaller than 0.2(λ/n) 3 have been designed. This represents an increase of almost three orders of(More)
Catechins, naturally occurring flavonoids derived from wine and green tea, are known to exhibit multiple health benefits. Epigallocatechin gallate (EGCG) is one of the most widely investigated catechins, but its efficacy in cancer therapy is still inconsistent and limited. The poor stability of EGCG has contributed to the disparity in the reported(More)
We report the detection of quantum confinement in single InAs-InP core-shell nanowires. The wires, having an InAs core with ∼25 nm diameter, are characterized by emission spectra in which two peaks are identified under high excitation intensity conditions. The peaks are caused by emission from the ground and excited quantized levels, due to quantum(More)
