However, let me would be very clear it is not a real or physical entity like an electron; electron hole is a mathematical concept, it means that if an electron does not exist in a space where it is supposed to exist we say that by not being present it has created a hole or if an electron migrates from a point to another it leaves behind So, let us I think most of us recall this when we studied our basic high school electric electricity, that this is a mathematical concept or just a concept I would say to represent absence of electrons in an energy band and we imagine this imagined as carrier electron is a negative charge carrier, this one is a positive charge carrier.
हालाँकि, मुझे यह स्पष्ट करना होगा कि यह एक इलेक्ट्रॉन की तरह वास्तविक या भौतिक इकाई नहीं है; इलेक्ट्रॉन होल्स (electron holes) एक गणितीय सिद्धांत है, इसका अर्थ है कि यदि कोई इलेक्ट्रॉन उस स्थान पर मौजूद नहीं है, जहां उसका अस्तित्व है, तो हम कहते हैं कि मौजूद नहीं होने से यह एक होल बना है या यदि इलेक्ट्रॉन एक स्थान से दूसरे स्थान पर जाता है तो वह पीछे एक होल छोड़ जाता है ।
