Fig. 46 The curves of C 1 versus carrier degeneracy under terahertz frequency in HD QFs of
(a) PbSnSe (b) PbSnTe and (c) PbTe, respectively
Fig. 47 The curves of C 2 versus carrier degeneracy under terahertz frequency in HD QF of
(a) PbSnSe (b) PbSnTe and (c) PbTe, respectively
of ternary material under constraints (E/E g ) 1 and electric field quantum limits
have been drawn for (a) the band structure contains 3 energy band constants and
(b) the band structure contains 2 energy band constants respectively. In Figs. 59 and
60 the curves of the C 1 versus E 0 in n-channel accumulation layers of quaternary
materials 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 2 energy band constants respectively. In Figs. 61 and
