Semiconductors - ka hoʻokohu 'a me ka Mea Maluna

noho Digital mea hana increasingly nui i kūlana i loko o kēiaʻano uilaʻoe. Mea maalea, e holo ana ma inoaia e komo ilokoʻaneʻane a pau noi - kulanakauhale a me ka hanalima pono, toys, wikiō, Radio-TV technician, a no laila, ma luna o. Eia naʻe, eia nō laulā a me ka Analog discrete hehee wale. A, mea uholo uila maalea - ka loa i loko o kēia? Inoaia.

Pehea i ia mau manaʻo? Ke kumu no ia mau manaʻo i mea uholo uila waiwai i semiconductors. E like me kona pou 'ano a me ka waiwai ka mea, i kona külana ma waena o insulators a me conductors. Hanohano nō hoʻi nā hiʻona o - he kaukaʻi o conductivity ma ka Ambient ana wela, ke ano o ka waiwai o ionizing pāhawewe, a me ka malamalama, a me ka huikala lehulehu. Semiconductors i ka hola o ka like 'ia o nā' ano.

Ma ke kaʻina hana o ka pili ana ka uila kala pono i loko o kekahi waiwai ke komo wale lawe lima kauoha nā moku halihali mokulele. Ka oi Mobile kauoha nā moku halihali mokulele no pa alima ka leo o ka waiwai, me ka oi aku o ka pou conductivity. Ma ke hooheheeiaʻaneʻane a pau o na electrons ua noa, a me keia hiki aku ai i kā lākou kiʻekiʻe conductivity. Ma semiconductors a me dielectrics Media mea nui emi no laila, a me ka oi resistivity.

Na pou eiiiiiaiou e like semiconductors haʻi ana wela kaukaʻi o ka resistivity. Me ka ulu ana wela, ka mea, ua ana hoemiia.

Penei, mea uholo uila maalea - kēia mau mea mīkini uila no i hana ma muli o keʻano o ka hanaʻana i loko o kekahi waiwai i kapaia semiconductors. Ka mea, loaʻa ka widest noi. No ka laʻana, i ka uila no a me ka uila 'enekinia, mea uholo uila i na mea maalea i hoʻohana e hoohuli i keʻano o nā lepa, kā lākou alapine (frequency), ikaika hawewe, a me nā mea kiko'î. Ma ia mana no na mea paahana, e hoʻohana no ka ikehu huli ana.

mea uholo uila maalea hiki ke hoʻolaha ma naʻano likeʻole. No ka laʻana, ikeia ki ina hana like o ka Mea Maluna e like me ka loina o ka hana, e like me ka manao ma ka manao, ka hana 'ike loea o ke kula a me ka mau o ke noi, no nāʻano o nā pono hana.

Eia naʻe, loaʻa ka mea, no laila,-kapaia kāna mau 'ōlelo papa, a emi iho i ka mea uholo uila noonoo. Mau papa nā:

- Electroconversion maalea, e hiki wale ua hoohuliia i loko o nā Hawaiʻi;

- Optoelectronic, i hoʻolilo i ka malamalama i loko o ka uila peahi ana a me ka Hope versa;

- paa-moku'āina kiʻi converters;

- thermoelectric maalea, e hiki ke hoʻolilo i thermal ikehu i loko o uila ikehu;

- magneto a me ka electromagnetic a manaʻo;

- piezoelectric a me ke kanana nei.

A hoʻokaʻawale papa o nā mea e like me mea uholo uila maalea hiki ke kapaia noniakahi wahi i puhi ai, i mea ana i hui pūʻia, a laila hui 'ia o nā' ano i loko o ka hoʻokahi lima kūlana kiʻekiʻe.

Nō kāu, e hua mai mea uholo uila manao maalea i loko o ka hale noho pālolo a ea, akā, ma laila nō nā koho no unpackaged.
