Fig. 23 The curves of C 1 versus d z under terahertz frequency in ternary material for (a) the band
structure contains 3 energy band constants, (b) the band structure contains 2 energy band constants
and (c) where the band structure defined by a single energy band constant
Fig. 24 The curves of C 1 versus d z under terahertz frequency in quaternary materials for (a) the
band structure contains 3 energy band constants, (b) the band structure contains 2 energy band
constants and (c) where the band structure defined by a single energy band constant
