Paper Abstract

Mechanism of Sb-SR (Sb-type super-resoluiton near-field structure) was studied. Experimental results show that the super-resolution performance of amorphous Sb-SR is considerably better than crystal Sb-SR. Considering that Sb is a semi-conductor with small energy gap, a three-order nonlinear response of surface plasmons is deduced to explain the performance of amorphous Sb-SR. Estimation is made and the calculated results are in agreement with the experimental results. Under the new approach, other semiconductors with small energy gap may possibly possess super-resolution performance.
