band offset

基本解釋

帶偏
Finally, we discuss the electronic properties of BaTiO_3-ZnO heterostructure from its interfacial atomic structures. Band offset calculations show that electrons in ZnO atomic layers will be prevented from transmitting to BaTiO_3 side, providing possibilities for manufacturing ferroelectric-semiconductor heterostructure-based devices.
最後，從界麪原子結(jié)搆出發(fā)深入討論了BaTiO_3-ZnO異質(zhì)結(jié)搆的電子特性，其中帶偏計算表明電子從ZnO一側(cè)難以越過界麪勢壘到達(dá)BaTiO_3側(cè)，從而爲(wèi)研制基於鉄電-半導(dǎo)躰異質(zhì)結(jié)搆的納米器件提供了可能。

As for the theoretical analysis and calculation, we use both the classical analytical Anderson model and novel numerical C-V Matching method to analyze the band structure of the nc-Si:H/c-Si, and successfully obtain the band offset and interface charge density parameters.
