Izici ze-elekthronikhi zamafilimu azacile zihluke kakhulu kulezo zempahla eyinqwaba, futhi eminye imiphumela ebonakalayo eboniswa kumafilimu amancane kunzima ukuyithola ezintweni eziyinqwaba.
Ngezinsimbi eziningi, ukumelana kuncipha ngenxa yokwehla kwezinga lokushisa. Emazingeni okushisa aphezulu, ukumelana kunciphisa kanye kuphela ngokushisa, kuyilapho emazingeni okushisa aphansi, ukumelana kunciphisa izikhathi ezinhlanu ngokushisa. Nokho, kumafilimu amancane, kuhluke ngokuphelele. Ngakolunye uhlangothi, ukumelana namafilimu amancane kuphakeme kunokwensimbi ngobuningi, futhi ngakolunye uhlangothi, ukumelana namafilimu amancane kuncipha ngokushesha kunokwensimbi ngobuningi ngemva kokuncipha kwezinga lokushisa. Lokhu kungenxa yokuthi endabeni yamafilimu amancanyana, umnikelo wokuhlakazeka komhlaba ukumelana mkhulu.
Okunye ukubonakaliswa kwe-conductivity yefilimu ezacile engavamile ithonya lamagnetic ekuphikisweni kwefilimu encane. Ukuphikiswa kwefilimu encane ngaphansi kwesenzo sensimu yamagnetic yangaphandle kukhulu kunokwe-block efana nempahla. Isizathu siwukuthi uma ifilimu iqhubekela phambili eduze komzila ovunguzayo, inqobo nje uma i-radius yomugqa wayo ozungezayo inkulu kunobukhulu befilimu, ama-electron azosakazeka phezulu ngesikhathi senqubo yokunyakaza, okuholela ekubeni kube nokuphikiswa okwengeziwe, okuholela ekubeni ukumelana kwefilimu kube kukhulu kunoko kwebhulokhi njengomsebenzi. Ngesikhathi esifanayo, izophinde ibe mkhulu kunokumelana kwefilimu ngaphandle kwesenzo somkhakha wamagnetic. Lokhu kuncika kokumelana nefilimu endaweni kazibuthe kubizwa nge-Magnetoresistance effect, ngokuvamile esetshenziselwa ukukala amandla kazibuthe. Isibonelo, i-a-Si, i-CulnSe2, ne-CaSe ifilimu encane yamaseli elanga elanga, kanye ne-Al203 CeO, CuS, CoO2, CO3O4, CuO, MgF2, SiO, TiO2, ZnS, ZrO, njll.
