Kuwanda kwekupisa kwesimbi kunodzivirira firimu kunosiyana zvichienderana nekukora kwefirimu, mafirimu matete haana kunaka, mafirimu makobvu akanaka, uye mafirimu makobvu akafanana asi haana kufanana nezvinhu zvakawanda. Kazhinji, kuwanda kwekupisa kwekudzivirira kunochinja kubva pane zvisina kunaka kuenda kune zvakanaka sezvo ukobvu hwefirimu hunowedzera kusvika kumakumi e nanometers.
Pamusoro pezvo, mwero wekubuda kwemvura unokanganisawo mwero wekudziya kwekupisa kwemafirimu esimbi. Mwero wekudziya wakaderera unogadzirwa nefirimu wakasununguka, maerekitironi ari pamusoro pechipingamupinyi chayo uye kugona kugadzira conductivity hakuna kusimba, pamwe chete neoxidation uye adsorption, saka kukosha kwekudziya kwakakwira, mwero wekudziya kwekupisa kwekudzivirira uri mudiki, kana kutoti negative, nekuwedzera kwemwero wekudziya, mwero wekudziya kwekupisa kwekudzivirira kwekuchinja kudiki kubva kune hombe, kubva kune negative kuenda kune positive. Izvi zvinokonzerwa nemwero wakaderera wekudziya kwefirimu wakagadzirwa nekuda kweoxidation ye semiconductor properties, mwero wekudziya kwekupisa kwe resistance of negative values. Mafirimu akagadzirwa nemwero wekudziya wakakwira anowanzova nemetallic properties uye ane mwero wekudziya wekupisa we positive resistance.
Sezvo chimiro chefirimu chichichinja zvisingadzoreki nekupisa, chiyero chekupisa chinodzivisa uye chinodzivisa chefirimu chinochinjawo nekupisa kwechikamu chekufukidza panguva yekubuda kwemvura, uye kana firimu racho rikatetepa, shanduko yacho inonyanya kukura. Izvi zvinogona kufungwa nezvazvo semhedzisiro yekuchinja kwemakemikari kunokonzerwa nekubuda kwemvura zvakare uye kugoverwa patsva kwezvidimbu zvefirimu rechimiro chechitsuwa kana tubular pane substrate, pamwe nekupararira kwelattice, kupararira kwetsvina, kupararira kwezvikanganiso zvelattice, uye oxidation.
