Micro-scale patterned arrays and nano-scale rough morphology are promising for improving the light-extraction performance of GaN-based thin film light-emitting diodes (TFLEDs). while the light-extraction mechanisms of the multiscale architectures combining these two structures have not been investigated yet. In this report. we have adopted a pattern transfer and wet etching combined m... https://hollandscountryclothinges.shop/product-category/work-boots/
