Saboda yanayin kalaman wannan barbashi, zai iya ta hanyar shamaki da aka haramta. Don yin wannan, electron dole ne ya sami wani adadin kuzarin "resonance". Lokacin da aka yi amfani da ƙaramin ƙarfin har zuwa 2,6 V a cikin tantanin halitta da masana kimiyya suka haɓaka, electrons sun fara yin rami ta hanyar shinge mai Layer uku da aka yi da kayan indium arsenide da aluminum antimonide (InAs / AlSb).
