Fraunhofer IISB (Cibiyar Hadakar Tsarin da Fasahar Na'ura) da ke Erlangen da kuma kamfanin kera tsarin plasma na microwave da rediyo PVA TePla AG da ke Wettenberg suna haɗa ƙwarewarsu a cikin wani dakin gwaje-gwaje na haɗin gwiwa don samar da lu'ulu'u na aluminum nitride (AlN).
A matsayinmu na ƙasashen Turai na farko, wannan haɗin gwiwa yana ba da damar samar da ƙananan ƙwayoyin AlN masu siffar monocrystalline tare da diamita na inci 2 don dalilai na bincike da ci gaba. Wannan yana inganta samuwar ƙwayoyin AlN a Turai sosai, wanda hakan ke hanzarta haɓaka na'urori da tsarin da ke tushen AlN da kuma sauye-sauyensu zuwa aikace-aikacen masana'antu.
Nitride na aluminum yana ɗaya daga cikin kayan aiki mafi kyau ga ƙarni na gaba na kayan lantarki masu aiki mai kyau. A matsayinsa na semiconductor mai faɗi-faɗi (UWBG), AlN yana buɗe sabbin damammaki a cikin photonics, lantarki mai ƙarfi, na'urorin lantarki masu yawan mita, da na'urorin lantarki waɗanda ke aiki a ƙarƙashin yanayi mai tsauri. Zuwa yanzu, ƙarancin abubuwan da ke cikin AlN masu inganci, babban yanki da kuma masu araha suna hana ci gaban tsarin lantarki na AlN.
"Tare da dakin gwaje-gwaje na hadin gwiwa, muna shimfida harsashin tabbatar da wadatar kayayyakin AlN daga Turai, ta haka ne za mu bude sabbin damammaki ga sabbin na'urorin AlN masu inganci," in ji Dr Sven Besendörfer, shugaban rukuni na kayan nitride kuma mai alhakin bunkasa kayan AlN a Fraunhofer IISB. "Tare da PVA TePla, muna ba da gudummawar kwarewarmu a fannin bunkasa lu'ulu'u na masana'antu, ta haka ne za mu samar da abubuwan da ake bukata don canja wurin zuwa aikace-aikacen siminti."
Fasahar kayan aiki da aka tabbatar ta dace da ƙwarewar tsarin mallakar
A cikin dakin gwaje-gwaje na haɗin gwiwa, Fraunhofer IISB tana amfani da fasahar sarrafa PVT (jiki na jigilar tururi) don samar da lu'ulu'u masu girman inci 2 na AlN. A cikin wannan tsari, ana tururin foda na AlN a cikin wani bututun ruwa a yanayin zafi sama da 2000°C sannan a saka shi a kan lu'ulu'u iri. PVA TePla tana samar da tsarin PVT don wannan dalili, waɗanda aka riga aka yi amfani da su a duk duniya don lu'ulu'u masu girman inci 8 na silicon carbide (SiC) kuma yanzu an daidaita su musamman don haɓaka lu'ulu'u na AlN masu inci 2.
Saboda ƙwarewar da Fraunhofer IISB ya bayar wajen aiwatar da aikin, ƙungiyar PVA TePla ta sami damar samar da lu'ulu'u na AlN masu inganci iri ɗaya a cikin kayan aikinta. Ƙungiyar Joint Lab ta mai da hankali kan samar da ƙananan lu'ulu'u na AlN mai inci 2. Yanzu ana ƙara yawan samarwa a hankali don inganta daidaiton tsari, sake samarwa, yawan amfanin ƙasa da tsarin farashi.
"Tare da aluminum nitride, muna tsara sabuwar fasahar zamani bayan SiC," in ji Dr Jan Pfeiffer, mataimakin shugaban R&D a PVA TePla. "Ta hanyar dakin gwaje-gwajen hadin gwiwa, za mu iya hada kwarewar kayan aikinmu kai tsaye tare da ilimin tsarin Fraunhofer IISB, wanda zai ba mu damar bayar da mafita ga abokan cinikinmu na duniya a farkon lokaci," in ji shi.
