4. G. S. Kino and H. Gautier [J. Appl. Phys. 44, 5219 (1973)] have developed a theory based on the “varactor model” under flat‐band and open‐circuit conditions. JAPIAU0021-8979
5. H. Hayakawa and K. Hoh (private communication) have tried to extend Kino‐Gautier’s theory to discuss the gate‐voltage dependence under open‐circuit conditions.
