請(qǐng)問(wèn) 平帶電位到底該怎么理解??flat-band potential?尤其是半導(dǎo)體中的flat-band potential [ 來(lái)自科研家族 骷髏黨 ] |

flat band potential 是只施加電壓時(shí)半導(dǎo)體沒有band bending,這個(gè)電壓就叫做flat band potential. Usually, band bending forms at semiconductor/electrolyte interface. Flat band potential could be measured by Mott-schottky plot. Flat band potential is a good approximation of fermi energy at n-type semicondutor. Therefore, The conduction band potentials of n type semiconductor was very close to the flat band potential 平帶電勢(shì):是指在半導(dǎo)體和電解液的界面,沒有多余的電荷存在,沒有電場(chǎng)和空間電荷區(qū),以至于半導(dǎo)體的導(dǎo)帶和價(jià)帶不發(fā)生能帶彎曲,此時(shí)半導(dǎo)體的電極電勢(shì)即為平帶電勢(shì). |
