摘要：
Chiral sculptured thin films (STFs) are periodically anisotropic, and exhibit the circular Bragg phenomenon over a certain wavelength regime on axial excitation. Among the key deposition parameters,for the growth of a chiral STF is the so-called vapor incidence angle chi(nu) Analysis based on data on the related columnar thin films (CTFs) shows that pseudo-isotropic values of chi(nu) can exist. Similarly, a maximum-bandwidth value of chi(nu) is also shown to be possible. (C) 2002 Wiley Periodicals, Inc.
