LEEM-10 Ongororo Zvishandiso zvePN Junction Hunhu
Hunhu hunhu hwePNP junction ndeimwe yezvakakosha zvirimo mukudzidzisa kweyakajairika fizikisi, semiconductor fizikisi uye zvemagetsi. Boltzmann anogara aripo chinhu chinogara chichiitika mufizikiki. Mune fizikiki kuyedza kudzidzisa zvinhu, pakave paine zviyero zvezvinhu zvakakosha zvemuviri, senge huwandu hwemagetsi, chiyero chemasschaji, Planck kugara, nezvimwewo, asi pane zvishoma zviyero pachiyero cheBoltzmann chinogara chiripo uye kudzidza kwekuparadzirwa kweBoltzmann. Iyo JN junction yemuviri zvivakwa muedzo inogadzirwa nekambani yedu inogona kushandiswa kuyera izvo zvepanyama zvivakwa uye Boltzmann inogara iripo yePN junction, uye kudzidza nzira nyowani yekushaya simba kwazvino kuyerwa.
Kuedza
1. Measure PN junction diffusion yazvino maringe nejunction voltage, uye uwane Boltzmann inogara iripo
2. Gadzira yazvino-voltage shanduri uchishandisa anoshanda ma amplifaya kuyera isina kusimba ikozvino
3. Pimisa pn junction voltage maringe netembiricha, uye uwane kunzwisisika kwejunction voltage netembiricha
4. Tora unorambidzwa bandwidth yesilicon zvinhu pa0 K anenge
5. Pima tembiricha uye kupikisa kwemagetsi uchishandisa platinamu kuramba uye DC bhiriji nzira
