Qalabka elektaroonigga ah ee filimada khafiifka ah aad ayay uga duwan yihiin kuwa alaabada bulk, iyo saamaynta jireed ee lagu soo bandhigo filimada khafiifka ah way adagtahay in laga helo agabka badan.
Biraha badan, caabbinta ayaa hoos u dhacda sababtoo ah hoos u dhaca heerkulka. Heerkulka sare, iska caabintu waxay hoos u dhacdaa hal mar oo keliya heerkulka, halka heerkulka hooseeya, iska caabintu waxay hoos u dhigtaa shan jeer heerkulka. Si kastaba ha noqotee, filimada khafiifka ah, gabi ahaanba way ka duwan tahay. Dhanka kale, iska caabbinta filimada khafiifka ah ayaa ka sarreeya birta bulk, dhinaca kale, iska caabinta filimada khafiifka ah ayaa si dhakhso ah hoos ugu dhacda marka loo eego biraha bulk ka dib marka heerkulku hoos u dhaco. Tani waa sababta oo ah marka laga hadlayo filimada khafiifka ah, wax ku biirinta faafinta dusha sare ee caabbinta ayaa ka weyn.
Muujin kale oo ka mid ah dhaqdhaqaaqa filimka khafiifka ah ee aan caadiga ahayn waa saameynta duurka magnetic on caabbinta filimka khafiifka ah. Iska caabbinta filimka khafiifka ah ee hoos yimaada ficilka magnetic dibadda ayaa ka weyn kan block sida walxaha. Sababta ayaa ah in marka filimku uu horay u sii socdo oo uu sii socdo wareegga wareegga, ilaa inta uu ka weyn yahay dhumucda xayndaabkiisa filimka, electrons ayaa ku kala firdhi doona dusha sare inta lagu jiro habka dhaqdhaqaaqa, taas oo keeneysa iska caabin dheeraad ah, taas oo keenaysa caabbinta filimku inuu ka weyn yahay kan block sida walxaha. Isla mar ahaantaana, waxay sidoo kale ka weynaan doontaa iska caabbinta filimka iyada oo aan la qaadin ficil magnetic field. Ku-tiirsanaantan iska caabbinta filimka ee goobta magnetic waxaa loo yaqaan saamaynta Magnetoresitance, kaas oo inta badan loo isticmaalo in lagu cabbiro xoogga goobta magnetic. Tusaale ahaan, a-Si, CulnSe2, iyo CaSe filimada khafiifka ah unugyada qoraxda, iyo sidoo kale Al203 CeO, CuS, CoO2, CO3O4, CuO, MgF2, SiO, TiO2, ZnS, ZrO, iwm.
