The Roles of Surface Roughness W. Wood. observed an “anomalous” optical absorption by thin alkali metal films, which he attributed to their granular structure. Until fairly recently, the focus of the investigations has been almost entirely on the effect of surface roughness on the linear optical response of metals, e.g., the ref作者: 四牛在彎曲 時(shí)間: 2025-3-22 15:06 作者: 狗舍 時(shí)間: 2025-3-22 20:36
