Saddexda tilmaame ee waaweyn ee xulashada garaafyada semiconductor

Warshadaha semiconductor-ka waa warshadaha sayniska iyo tignoolajiyada soo baxaya, taas oo soo jiidatay dareenka weyn sanadihii ugu dambeeyay, shirkado aad u badan ayaa bilaabay inay galaan warshadaha semiconductor, iyo graphite wuxuu noqday mid ka mid ah agabka lagama maarmaanka u ah horumarinta warshadaha semiconductor. Semiconductors waxay u baahan yihiin inay isticmaalaan korantada korantada ee graphite, sababtoo ah kaarboonka kaarboonka ee garaafka, ayaa ka sii fiicnaanaya korantada korantada, guud ahaan waxay u baahan yihiin in la tixgeliyo tilmaamayaasha: cabbirka qaybta, caabbinta kulaylka, nadiifnimada.

Cabbirka hadhuudhku wuxuu u dhigmaa tirooyinka mesh ee kala duwan, iyo qeexitaannada waxaa lagu muujiyey tirooyinka mesh. Nambarka mesh waa tirada godadka, taas oo ah, tirada godadka halkii inji oo labajibbaaran. Guud ahaan marka la hadlo, lambarka mesh * aperture (micron) = 15000. Tirada mesh ee graphite-ka-qaadista ee weyn, cabbirka qaybta yar, ayaa ka sii wanaagsan waxqabadka saliidda, waxaa loo isticmaali karaa berrinka wax soo saarka alaabta saliidda. Cabbirka qaybta loo isticmaalo warshadaha semiconductor waa in ay ahaataa mid aad u fiican, sababtoo ah way fududahay in la gaaro saxnaanta farsamaynta, xoogga cadaadiska sare, iyo khasaaraha yar, gaar ahaan caaryada sintering, oo u baahan saxnaanta processing sare.

Xajmiga qaybinta, sida: 20 mesh, 40 mesh, 80 mesh, 100 mesh, 200 mesh, 320 mesh, 500 mesh, 800 mesh, 1200 mesh, 2000 mesh, 3000 mesh, 5000 mesh, 5000 mesh, 0,010 mesh ganaaxa ugu badan ayaa noqon kara 15,000 mesh.

Alaabooyin badan oo ka mid ah warshadaha semiconductor waxay u baahan yihiin in si joogto ah loo kululeeyo, si loo kordhiyo nolosha adeegga qalabka, taas oo u baahan garaafyada korantada si ay u yeeshaan sifooyinka soo socda: isku-kalsooni heer sare ah iyo iska caabbinta heerkulka sare.

Shuruudaha wax soo saarka garaafyada ee warshadaha semiconductor waa: nadiifnimada sare, ka sii fiican, gaar ahaan aaladaha graphite ee taabta inta u dhaxaysa labada, haddii ay ku jiraan waxyaabo badan oo wasakh ah, waxay wasakhayn doonaan walxaha semiconductor. Sidaa darteed, waxaan u baahanahay inaan si adag u xakameyno nadiifnimada graphite conductive, iyo sidoo kale waxaan u baahanahay inaan ku daaweyno garaafyada heerkulka sare si loo yareeyo heerka cawl.
