insight - Bulk Photovoltaic Effect
ZnGeP$_2$ 中的大體積光伏效應及其化學勢增強的費米面介導機制
本文研究了 ZnGeP$_2$ 中體積光伏效應的增強，發現通過調節化學勢，可以顯著提高移位電流和圓形光電流電導率，而費米面狀態在其中起著關鍵作用。
Fermi Surface Mediated Enhancement of Bulk Photovoltaic Effect in ZnGeP2 with Chemical Potential
The bulk photovoltaic effect (BPVE) in ZnGeP2 can be significantly enhanced by tuning the chemical potential, which modifies the Fermi surface and leads to increased shift and circular photogalvanic current conductivities.
Excitonic Enhancement of the Shift Current in Bulk Photovoltaics: A Many-Body Perspective
The shift current in bulk photovoltaic materials is significantly enhanced by excitonic effects, particularly in materials with strong electron-hole interactions, due to the increased likelihood of k-space overlap between nearly-degenerate excitons.
