Following femtosecond (fs) laser pulse irradiation, the formation of a new type of low-spatial-frequency laser-induced periodic surface structure (LSFL) patterns, namely, omnidirectional LSFLs (OD-LSFLs) with the periodic ordering of their orientatio

Light-emitting diodes (LEDs) convert 15% of the applied energy to light and the remaining 85% to heat. High-power chips increasingly emit more heat, resulting in performance degradation and ultimately translating into shorter life expectancy of LED p
