سلام
من مفهوم خمیدگی باند رو درک نمیکنم.
the presence of majority hole accumulation produces a strong band bending at perovskite−electron-selective contact interface. This band bending reveals that electronic charge injection at electron-selective contact occurs via tunneling. a result, the electric field formed at the interface due to the cation and hole accumulation that produce the band bending.
میشه لطفا یه نفر مفهوم این جملات توضیح بده
ممنون
