Fig. 61 The curves of C 1 versus (electric quantum limit) at terahertz frequency in n-channel
accumulation layers of ternary materials where (E/E g ) 1 for (a) the band structure containing
3 energy band constants and (b) the band structure containing 2 energy band constants
materials under constraints (E/E g ) 1 and (E/E g ) 1 electric field quantum
limits for (a) the band structure contains 3 energy band constants and (b) the band
structure contains 2 energy band constants respectively. In Figs. 76 and 77 the curves
of C 2 versus x in accumulation layers of ternary material have been drawn under
constraints (E/E g ) 1 and (E/E g ) 1 electric field quantum limits for (a) the
band structure contains 3 energy band constants and (b) the band structure contains
