APAKAH MAKSUD THERMIONIC dalam CORSICA?
Pelepasan termionik
Pelepasan termioni adalah aliran udara yang disebabkan oleh pembawa caj dari permukaan atau di atas penghalang potensi tenaga. Ini berlaku kerana tenaga haba yang diberikan kepada pembawa mengatasi potensi mengikat, juga dikenali sebagai fungsi kerja, logam. Pembawa caj boleh menjadi elektron atau ion, dan dalam kesusasteraan yang lebih tua kadang-kadang disebut sebagai "termion". Selepas pelepasan, caj yang bersamaan dengan magnitud dan bertentangan dengan tanda kepada jumlah cas yang dipancarkan pada mulanya ditinggalkan di kawasan pemancar. Tetapi jika pemancar disambungkan ke bateri, caj yang ditinggalkan akan dinetralkan oleh caj yang dibekalkan oleh bateri kerana syarikat penerbangan caj yang dipancarkan bergerak dari pemancar, dan akhirnya pemancar akan berada dalam keadaan yang sama seperti sebelum pelepasan. Contoh klasik pelepasan termionik adalah pelepasan elektron dari katod panas ke dalam vakum dalam tiub vakum. Katod panas boleh menjadi filamen logam, filamen logam bersalut, atau struktur berasingan logam atau karbida atau borida logam peralihan. Pelepasan vakum dari logam cenderung menjadi penting hanya untuk suhu melebihi 1000 K.
