a Multipole expansion of the total extinction of a single chiral gold nanoparticle of 180 nm. b, c Surface charge distribution under linear excitation (x-polarization) with 635 nm and 780 nm, respectively. d, e E-field enhancement and its corresponding current distribution in the yz plane (yellow arrow) at x = −80 nm under linear excitation (x-polarization) with 635 nm and 780 nm, respectively. f, g Difference between the E-field enhancement under LCP and RCP excitation in the xy plane, which is the interface between the chiral gold nanoparticle and IGZO under 635 nm and 780 nm light excitation, respectively. The integrated value is −1.20 \(\times\) 10−15 m2 (635 nm) and 7.10 \(\times\) 10−15 m2 (780 nm).
