Muskawar Fisikai na Semiconductors?
Bayani na Muskawar Fisikai na Semiconductors
Muskawar fisikai na semiconductors yana nufin bincike masu tattalin karamin jirgin ruwa da ke kan mafi tattalin karamin jirgi da mafi hanyar tattalin karamin jirgi, musamman wadannan mutanen da ake yi da silikon da germanium.
Kasashen Semiconductors
Semiconductors suna da tattalin karamin jirgin ruwa mai tsarki da kuma tsarin tattalin karamin jirgin ruwa mai haske, wanda ya nuna cewa tattalin karamin jirgin ruwan su ke zama da gaskiya ne idan harin ya faru.
Covalent Bonding
Abubuwan elektron da ke cikin atomon semiconductors suna da muhimmanci a nan da aka sanya wa mutanen a crystal. Sanya ta atomon yana faru saboda har da atomin yake so in samun shida biyu a wasu itacen da ke cikin rarrabbin da ke cikin wannan atom.
Har da atomi semiconductors yana da abubuwa dudu a cikin elektron da ke ciki, kuma zai iya share abubuwa dudu daga atomon da suke a nan don in kammala shida biyar a rarrabbin da ke cikin atom. Wannan sharing of electrons yana ba da covalent bonds.
Har da atomi semiconductors yana sanya da covalent bond biyar da atomon da suke a nan a crystal. Yana nufin cewa, covalent bond biyar yana faru da kowane atomi da suke. Rarrabi a nan yana nuna covalent bonds da aka faru a crystal na germanium.
A crystal na germanium, kowane atomi yana da shida biyar a rarrabbin da ke cikin. Amma a atomi germanium da ba a gano, akwai shida biyar. Rarrabi na farko yana da shida biyu. Rarrabi na biyu yana da shida biyar. Rarrabi na uku yana da shida takwas. Kuma shida dudu su ke a rarrabbin na hudu da karamin.
Amma a crystal na germanium, kowane atomi yana share abubuwa dudu daga atomon da suke a nan don in kammala shida biyar a rarrabbin da ke cikin. Hakan yana nufin cewa kowane atomi a nan yana da shida biyar a rarrabbin da ke cikin.
Sanya ta covalent bonds yana ba da kowane abubuwa da atom, bane da abubuwan elektron da ba suka faru a ideal crystal na semiconductors. Atomon suna da yanayin da suka daɗi saboda wannan sanya, wanda yake bayyana crystal structure na semiconductors.
Energy Band Theory
Semiconductors suna da energy gap mai tsarki a kan valence band da conduction band, wanda yana ba da abubuwan elektron su karfin da suka faru da karamin jirgin ruwa idan ana bayar energy.
