Sib piv Boron Nitride, Graphene thiab Molybdenum Disulfide

Boron nitride, graphene, thiab molybdenum disulfide yog txhua yam khoom siv nrog cov khoom tshwj xeeb thiab kev siv.

Boron nitride yog xim dawb, khoom siv nrog thermal thiab tshuaj lom neeg ruaj khov. Nws muaj lub siab melting point thiab tiv taus oxidation, ua rau nws yog ib qho khoom siv zoo rau kev siv kub. Tsis tas li ntawd, boron nitride nthuav tawm cov khoom siv hluav taws xob zoo heev thiab feem ntau siv los ua cov khoom siv dielectric. Nws cov khoom tshwj xeeb kuj tau pom cov lus cog tseg hauv thaj chaw ntawm optoelectronics thiab photonics.

Graphene, ntawm qhov tod tes, yog cov khoom siv ob sab uas muaj ib txheej ntawm cov pa roj carbon atoms uas tau ntim rau hauv hexagonal lattice. Graphene muaj cov khoom siv hluav taws xob txawv txawv, thermal, thiab cov khoom siv kho tshuab, ua rau nws muaj ntau yam zoo kawg thiab muaj txiaj ntsig hauv ntau thaj chaw. Nws yog cov khoom siv paub zoo tshaj plaws, tus neeg xyuas pib zoo ntawm hluav taws xob thiab cua sov, thiab pob tshab. Vim nws cov khoom tshwj xeeb, graphene tau kawm thiab tsim rau cov ntawv thov suav nrog cov khoom siv hluav taws xob hloov tau, roj teeb, roj hlwb, thiab cov sensors.

Molybdenum disulfide yog lwm yam khoom siv ob sab uas tau txais kev pom zoo nyob rau xyoo tas los no vim nws cov khoom siv hluav taws xob zoo kawg nkaus, txhua yam, thiab kho qhov muag. Nws yog ib qho semiconductor nrog bandgap, uas ua rau nws muaj txiaj ntsig zoo rau kev siv hluav taws xob. Nws kuj muaj cov cuab yeej kho qhov muag tshwj xeeb hu ua valley polarization, uas muaj peev xwm loj heev hauv thaj chaw ntawm optoelectronics. Tsis tas li ntawd, molybdenum disulfide tau pom cov lus cog tseg rau kev siv hauv lub zog cia khoom.

Zuag qhia tag nrho, txhua yam ntawm cov ntaub ntawv no muaj qhov zoo sib xws thiab kev siv txiav. Boron nitride zoo heev thermal thiab tshuaj stability ua rau nws zoo tagnrho rau high-temperature daim ntaub ntawv, thaum graphene lub extraordinary hluav taws xob, thermal, thiab mechanical zog ua rau nws pab tau nyob rau hauv ntau yam ntawm teb. Molybdenum disulfide cov khoom siv hluav taws xob tshwj xeeb, cov khoom siv kho qhov muag, thiab cov khoom siv kho qhov muag kuj ua rau nws cov khoom zoo siab rau kev tshawb fawb thiab kev loj hlob. Raws li kev tshawb fawb txuas ntxiv mus, nws zoo li txhua yam ntawm cov ntaub ntawv no tseem yuav muaj kev cuam tshuam loj rau kev tshawb fawb thiab thev naus laus zis.

Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
