Ungasitshela okwengeziwe ngomphumela wosawoti emiphumeleni? Ingabe kukhona uhlobo oluthile lomphumela we-capacitive we-double layer yama-ion enhlabathini?
Kungaba kuhle uma ungangitshela ulwazi olwengeziwe ngalokhu. Nginesifiso sokwenza izilinganiso zomswakama wenhlabathi ezinembile kakhulu.
Cabanga nje uma bekukhona umqhubi ophelele ozungeze inzwa (isibonelo, uma inzwa ibicwiliswe ensimbini ye-gallium ewuketshezi), ibingaxhuma amapuleti e-sensing capacitor komunye nomunye ukuze okuwukuphela kwe-insulator phakathi kwawo kube ungqimba oluncane oluhambisanayo ebhodini lesifunda.
Lezi zinzwa ezishibhile zokuthwala amandla, ezakhiwe kuma-chips angu-555, ngokuvamile zisebenza ngamaza angamashumi e-kHz, aphansi kakhulu ukuqeda ithonya likasawoti oncibilikisiwe. Kungase kube phansi ngokwanele ukubangela ezinye izinkinga ezifana nokumuncwa kwe-dielectric, okuzibonakalisa njenge-hysteresis.
Qaphela ukuthi ibhodi lezinzwa empeleni liyi-capacitor elandelanayo enesekethe elilingana nomhlabathi, elilodwa ohlangothini ngalunye. Ungasebenzisa futhi i-electrode engavikelwe ngaphandle kokugqoka ukuze uxhumeke ngqo, kodwa i-electrode izoncibilika ngokushesha enhlabathini.Ukusetshenziswa kwensimu kagesi kuzobangela ukugoqana endaweni engaphansi komhlabathi + emanzini. Ukuvumela okuyinkimbinkimbi kulinganiswa njengomsebenzi wensimu kagesi esetshenzisiwe, ngakho-ke ukugoqana kwezinto kuhlala kungemuva kwensimu kagesi esetshenzisiwe. Njengoba imvamisa yensimu esetshenzisiwe ikhula iye ebangeni eliphakeme le-MHz, ingxenye ecatshangelwayo ye-complex dielectric constant yehla kakhulu njengoba ukugoqana kwe-dipole kungasalandeli ukugoqana kwemvamisa ephezulu yensimu kagesi.
Ngaphansi kuka-~500 MHz, ingxenye ecatshangelwayo ye-dielectric constant ibuswa usawoti, futhi ngenxa yalokho, i-conductivity. Ngaphezu kwalezi zikhathi, i-dipole polarization izoncipha kakhulu futhi i-dielectric constant iyonke izoncika kokuqukethwe kwamanzi.
Izinzwa eziningi zezentengiselwano zixazulula le nkinga ngokusebenzisa amaza aphansi kanye nokusebenzisa ijika lokulinganisa ukuze kubhekwe izakhiwo zomhlabathi kanye namaza.
