SEMICONDUCTOR MATERIAL DESIGN

Yedu semiconductor zvinhu dhizaini mainjiniya anoshandisa chaiwo mamodule esoftware anopa maturusi akazvitsaurira ekuongorora semiconductor mudziyo mashandiro padanho rakakosha refizikisi. Mamodule akadaro akavakirwa paiyo drift-diffusion equations, uchishandisa isothermal kana nonisothermal yekufambisa modhi. Maturusi esoftware akadaro anobatsira pakuenzanisa maturusi akawanda anoshanda, anosanganisira bipolar transistors (BJTs), metal-semiconductor field-effect transistors (MESFETs), metal-oxide-semiconductor field-effect transistors (MOSFETs), insulated-gedhi bipolar transistors ( IGBTs), Schottky diodes, uye PN junctions. Multiphysics mhedzisiro inoita mabasa akakosha mukuita semiconductor mudziyo. Nezvishandiso zvine simba zvakadai zvesoftware, tinogona kugadzira mamodheru zviri nyore zvinosanganisira maitiro akawanda emuviri. Semuenzaniso, zvinopisa zvinopisa mukati memudziyo wemagetsi zvinogona kutevedzerwa uchishandisa kupisa kwekufambisa fizikisi interface. Optical transitions inogona kuiswa kuti itevedzere siyana yemidziyo yakadai sesolar cell, light-emitting diodes (LEDs), uye photodiodes (PDs). Yedu semiconductor software inoshandiswa kuenzanisa semiconductor zvishandiso zvine hurefu zviyero zve100's enm kana kupfuura. Mukati mesoftware, mune akati wandei efizikisi interfaces - maturusi ekugamuchira emodhi yekumisikidza kutsanangura seti yemuviri equation uye mamiriro emuganho, senge nzvimbo dzekumisikidza kutakurwa kwemaerekitironi nemaburi mumidziyo yesemiconductor, maitiro avo emagetsi ... nezvimwe. Iyo semiconductor interface inogadzirisa equation yePoisson pamwe chete nekuenderera equation kune ese maerekitironi uye gomba kuchaja mutakuri wezvisungo zvakajeka. Isu tinogona kusarudza kugadzirisa modhi neinogumira vhoriyamu nzira kana inogumira element element. Iyo interface inosanganisira mamodheru emhando ye semiconducting uye insulating zvinhu, mukuwedzera kune mamiriro emuganho eiyo ohmic contacts, Schottky contacts, magedhi, uye dzakasiyana-siyana dze electrostatic muganhu mamiriro. Zvimiro zviri mukati meiyo interface zvinotsanangura chivakwa chekufamba sezvo chichiganhurwa nekupararira kwevatakuri mukati mezvinhu. Chishandiso chesoftware chinosanganisira akati wandei akafanotsanangurwa ekufambisa modhi uye sarudzo yekugadzira tsika, inotsanangurwa nemushandisi modhiyo yekufamba. Mhando mbiri idzi dzemhando dzinogona kusanganiswa nenzira dzisiridzo. Imwe neimwe mobility modhi inotsanangura erekitironi inobuda uye kufamba kwegomba. Iko kubuda kwekufamba kunogona kushandiswa sechipo kune mamwe mamodhiyo ekufambisa, nepo equations inogona kushandiswa kusanganisa mobilities. Iyo interface ine zvakare maficha ekuwedzera Auger, Direct, uye Shockley-Verenga Hall recombination kune semiconducting domain, kana inobvumira kutsanangura yedu pachedu recombination rate. Kugovera kwedoping kunoda kutsanangurwa pakuenzanisira kwemidziyo yesemiconductor. Yedu software chishandiso chinopa doping modhi chimiro chekuita izvi. Nguva dzose pamwe neye doping profiles inotsanangurwa nesu inogona kutsanangurwa, kana fungidziro yeGaussian doping mbiri inogona kushandiswa. Tinogona kupinza data kubva kunze zvinyorwa zvakare. Yedu software chishandiso inopa yakawedzera Electrostatics kugona. Material database iripo ine zvivakwa zvezvinhu zvakati wandei.
