CO OZNACZA SŁOWO WORK FUNCTION
Funkcja robocza
W fizyce w stanie stałym funkcja robocza jest minimalną pracą termodynamiczną potrzebną do usunięcia elektronu z ciała stałego do punktu znajdującego się w próżni niezwłocznie na zewnątrz stałej powierzchni. Tutaj "natychmiast" oznacza, że ostateczna pozycja elektronu jest daleko od powierzchni na skalę atomową, ale nadal zbyt blisko stałej części, aby mogła wpływać na otaczające pola elektryczne w próżni. Funkcja robocza nie jest cechą materiału masowego, ale raczej właściwością powierzchni materiału.
Definicja słowa work function w słowniku
Definicja funkcji pracy w słowniku to minimalna energia wymagana do przeniesienia elektronu z punktu w bryle do punktu znajdującego się tuż za jego powierzchnią φ, Φ.

The material thus becomes an n-type semiconductor resulting in the reduction of
the work function. The thermionic emission constant A is also found to reduce
drastically (sometimes being less than unity) which tends to reduce the emission.
