However, as \u03bcLEDs shrink in size, the proportion of sidewall area increases, which resulted in non-radiative recombination effects and significantly reduce the external quantum efficiency (EQE). In general, the non-radiative recombination was resulted from the plasma etching during the mesa and isolation processing. To overcome the above issues, ion implantation can be used to insulate the structure of \u03bcLEDs among the pixcels.<\/p>\n<p>In this talk, ion implantation technology was introduced for the mesa and isolation processes of the devices. The effect of different ion sources with different incident energies on the \u03bcLEDs performance will be presented during the conference. More detained frequency response of \u03bcLEDs will also be presented.<\/p>\n<p><strong>Biography<\/strong><\/p>\n<p>Prof. Ray-Hua Horng received the B.S., and Ph.D. degrees from National Cheng Kung University and National Sun Yat-Sen University, Taiwan, in 1987 and 1993, respectively, all in electrical engineering.
