FIELD EMISSION SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Alan elektron emisyonu
Alan emisyonu, bir elektrostatik alan tarafından uyarılan elektronların emisyonudur. En yaygın bağlam, katı bir yüzeyden vakum içine alan emisyonudur. Bununla birlikte, alan emisyonu katı veya sıvı yüzeylerden vakum, hava, sıvı veya herhangi bir iletken olmayan veya zayıf iletken dielektrik içine gerçekleşebilir. Alan tarafından indüklenen elektronların yarı iletkenlerin iletken bandına değerlik değerlerinden yükseltilmesi de bir alan emisyonu şekli olarak kabul edilebilir. Terminoloji tarihsel bir olaydır çünkü yüzey foto efekti, termiyonik emisyon ve "soğuk elektronik emisyon", yani güçlü statik elektrik alanlarındaki elektron emisyonu ile ilgili fenomen, 1880'lerden 1930'lara kadar bağımsız olarak keşfedilmiş ve incelenmiştir. Alan emisyonu elemeler olmadan kullanıldığında, tipik olarak "soğuk emisyon" anlamına gelir. Saf metallerde alan emisyonu yüksek elektrik alanlarında gerçekleşir: gradyanlar tipik olarak metre başına 1 gigavolttan daha yüksektir ve iş fonksiyonuna kesinlikle bağlıdır. Alan emisyonuna dayalı elektron kaynakları bir takım uygulamalara sahiptir, ancak en yaygın olarak, mühendislerin önlemeye çalıştığı vakum arızası ve elektrik deşarj fenomeninin istenmeyen birincil kaynağıdır.
İngilizce sözlükte field emission sözcüğünün tanımı
Sözlükteki alan emisyonunun tanımı, yüksek elektrik alanına tabi tutulmuş bir katıdan veya sıvıdan gelen elektronların emisyonudur.
