Semiconductors - Tofiga ma le faavasegaina

meafaigaluega faatekinolosi nofoia se faateleina matafaioi taua i faaeletonika po nei. Masini e taufetuli i chips nei tuia toetoe talosaga uma - meafaigaluega municipal ma tau alamanuia, meataalo, vitio, faatekinisia leitio-TV ma isi. Ae peitai, o loo i ai tulaga pea ma elemene motu analog. Gata i lea, masini semiconductor - o le ute lea o chips nei.

E faapefea ona e pei o masini? O le faavae mo sea masini o mea semiconductor e semiconductors. E tusa ma lona eletise uiga ma meatotino latou faatulaga le va insulators ma conductors. foliga maoae o - a faalagolago o conductivity i luga o le vevela ambient, o le uiga o le aafiaga o ionizing leisa ma le malamalama, ma o le faasalaga mama. Semiconductors ai pe tusa o le mea lava e tasi o uiga.

I le faagasologa o le faia o se taimi nei eletise i so o se mea e mafai ona auai na o feaveaʻia feaveai totogi. O le feaveaʻia sili totogi feaveai i le voluma iunite o le mea, o le tele o le conductivity eletise. I uʻamea toetoe le electrons uma saoloto, ma o lenei e tau atu i latou conductivity maualuga. I semiconductors ma dielectrics ala o faasalalauga e sili itiiti ina ma sili resistivity.

O vaega eletise pei semiconductors faalagolago vevela folafola o le resistivity. Faatasi ai ma le faateleina o le vevela, e masani ona faaitiitia.

O lea, semiconductor masini - nei masini faaeletonika lea faagaoioia faavae i luga o faiga faapitoa i vailaau taʻua semiconductors. Latou maua o le talosaga ona lautele. Mo se faataitaiga, i le faaeletonika ma masini semiconductor inisinia eletise o loo faaaogaina e liliu a faailoilo eseese, o latou taimi, amplitude, ma isi tapulaa. I sea meafaigaluega mana o loo faaaogaina mo le liua malosi.

e mafai ona faavasegaina masini semiconductor i auala eseese. Mo se faataitaiga, iloa auala o le faavasegaina e tusa ma le mataupu faavae o le faatinoga, e pei ona faamoemoeina e le mamanu, le gaosia o tekinolosi o fanua ma vaega o le talosaga, o le ituaiga o mea.

Ae peitai, o loo faapea mai o vasega autu, lea e faamatalaina ai le masini semiconductor. O nei vasega e aofia ai:

- Electroconversion masini e na o ia e liua i isi tulaga faatauaina;

- Optoelectronic, lea e liliu le malamalama i ai se faailo i le eletise ma le isi foi itu;

- converters faatusa tulaga-mautu;

- masini thermoelectric e liliu malosi vevela i le malosi eletise;

- masini magneto ma eletise;

- piezoelectric ma avega.

O se vasega o le masini e pei o masini semiconductor mafai ona taʻua o matagaluega tuufaatasia, lea e masani lava ona fefiloi, i.e. tuufaatasi seti o uiga i se masini e tasi.

E masani lava, o loo gaosia masini semiconductor i se fale keramika po palasitika, ae o loo i ai avanoa mo unpackaged.
