shatkon boron nitride kaa sanshleshan

dou ayami shatkon boron nitride (2d h-bn) ee mein sambhaavit anuprayogon key saath graphene key saath tulaniya sanrachana kii ack samagri haye.jee. photonics.eendhan koshikaaen aur dwi-ayami visham sanrachanaon key liye ack substrate key roop mein. 2dee aich-bn graphene key liye samsanrachanaatmak haye, lekin jahaan graphene pravaahakiya haye, 2dee aich-bn ack vistrit antar avaahak haye.
2dee aich-bn filmon key guna filmon kii gunavatta parr bahut nirbhar karate hain. badey kshetron mein uchch gunavatta vaale 2dee aich-bn koo sanshleshit karna chunautipurna rhaa haye.
vishesh roop seey, polychrystalline aich-bn key chhote anaaj key aakar key parinamswarup kaee anaaj seemaaen hoti hain, joe avesh jaal aur uchch satah khurdarapan paida karati hain.
2dee aich-bn key utpaadan koo oopar-neeche aur neeche-oopar key tarikon mein vibhajit kiya jaa sakata haye. neeche kii or key tarikon mein, ack film koo satah parr ugaaya yaa jamaa kiya jaataa haye; oopar-neeche key tarikon mein, ack badee sanrachana koo taba taka cumm kiya jaataa haye jaba taka kii vaanchhit sthiti yaa sanrachana praapt naheen hoe jaati haye.
oopar-neeche key tareeke.
oopar-neeche key drishtikon key peechhe samanya vichaar thoke aich-bn lena, shatkon paraton key beach vaine dair walls balon koo todana aur aich-bn kii parinami dou-ayami sheet koo alag karna haye. inn takneekon mein mukhya roop seey yaantrik aur rasayanik exfoliation vidhiyaan shamil hain.
yaantrik exfoliation mein aich-bn kii paramanu sheets koo bhautik roop seey kheencha jaataa haye yaa ack dusare seey alag kiya jaataa haye. udaaharan key liye, graphene kii chadaron koo chhilka lagaane key liye niyamit chipakane vaali tape kaa upayog karna sabse prasiddh yaantrik exfoliation vidhiyon mein seey ack haye aur isi tarah kii takneekon kaa upayog aich-bn sheet banaane key liye bhee kiya jaa sakata haye. aam taur parr yaantrik exfoliation vidhiyon koo aich-bn nanocit banaane key saral tarikon key roop mein maanaa jaa sakata haye, lekin unaki upaj chhoti hoe sakati haye aur nirmit sanrachanaon kaa aakar aamtaur parr seemit hotaa haye. doosari or, utpaadit nanocit mein doshon kii sankhya rasayanik vidhiyon kii tulanaa mein cumm paaee gaee haye.
rasayanik exfoliation dichloroethane aur dimethylformide jaise taral vilayakon mein kiya jaataa haye. sonication kaa upayog aich-bn chrystal mein vaine dair walls balon koo todane key liye kiya jaataa haye joe vilaayak anuon koo paramanu paraton kaa vistaar karane kii anumati detaa haye. yeye vidhiyaan kaafee saral hain aur yaantrik exfoliation kii tulanaa mein adhik upaj bhee pradaan curr sakati hain, halanki namoone aasaani seey dooshit hotey hain.
