The results showed that Franz Keldysh effect of ZnS thin films resulted from electroabsorption of band tail. The shift of absorption edge to long wavelength was due to increase of absorption of local states near band edge.

- 在電場(chǎng)作用下，ZnS薄膜的Franz－Keldysh效應主要發(fā)生在帶尾附近，帶尾的局域態(tài)吸收受電場(chǎng)的影響引起的增加導致光學(xué)吸收邊的紅移。
