Fig. 18 The curves have been drawn at terahertz frequency for the normalized Fermi energy versus
concentration under strong electric field in accordance with the Kane model which contains three
energy band constants where E o = 10 8 V/m for Quantum wells of all the materials as taken in Fig. 1
Fig. 19 The curves have been drawn at terahertz frequency for the normalized Fermi energy versus
E 0 under the constraints (E/E g ) 1 for Kane model which contains three energy band constants
where d z = 30 nm and n o = 10 16 m −2 for Quantum wells of all the materials as taken in Fig. 1
