1. Mould Fabrication Vi bruger vores hjem-built nanoimprinting setup til fremstilling af den negative form efter ref. 6, men enhver alternativ nanoimprinting setup vil fungere fint. Alternativt kan en funktionaliseret polydimethylsiloxan (PDMS) mold kan også arbejde. <ol><li> Fabrikere eller købe en egnet mester bærer nanoskala mønster, der skal overføres.

Nanomoulding muliggør overførsel af nanopatterns på vilkårlige funktionelle materialer. Sammenligning af de enkelte procestrin i figur 1 og 2 viser det tætte forhold mellem nanomoulding og nanoimprinting. Den største forskel mellem nanomoulding og nanoimprinting er det yderligere materiale depositionstrinnet i figur 2e. Den resterende procesflow er identisk. Nanomoulding kan derfor foretages med alle tilgængelige nanoimprinting setup. ...

Nanopatterning har fået enorm betydning i mange områder af nanoteknologi og anvendte videnskaber. Mønster generation er det første skridt, og kan udføres ved top-down tilgange såsom elektron-stråle litografi eller bottom-up-tilgang baseret på selvsamling metoder såsom nanosphere litografi eller blokcopolymer litografi 1. Lige så vigtigt som mønster generation er mønster replikation. Udover fotolitografi, er nanoimprinting (figur 1) vist sig som et lovende alternativ især egnet til high-throughput large-area nanoskala mønsterdannelse med lave omkostninger 2-4. Mens fotolitografi kræver en mønstret maske, nanoimprinting bygger på en præfabrikeret mester struktur. Mønster overførsel fra masteren er almindeligvis udføres i en termoplastisk eller en UV-eller termisk hærdelige polymer. Men der er mange tilfælde, hvor det er ønskeligt at overføre mønstret direkte på et funktionelt materiale. &lt;p class = &quot;jove_content&quot;&gt; Her beskriver vi en replikations metode baseret på nanomoulding og layer transfer (figur 2), som vi for nylig indført i ref. fem at overføre nanoskala mønstre på funktionelle zinkoxid elektroder. Vores nanomoulding fremgangsmåde let kan implementeres, hvis et nanoimprinting konfigurationen findes. Nanomoulding give mulighed for at generaliseres til mange andre funktionelle materialer, materialer stakke og endda komplette udstyr, såfremt formen materialet vælges således, at det er foreneligt med materialet udfældningsproces (es). Som et eksempel vil vi præsenterer her nanomoulding af transparente, ledende zinkoxid (ZnO) elektroder deponeret ved kemisk dampudfældning (CVD), som finder deres anvendelse til at forbedre lys trapping i solceller 5.

nanomoulding of functional materials, a versatile complementary pattern replication method to nanoimprinting

Vi beskriver en nanomoulding teknik, som muliggør billig nanoskala mønsterdannelse af funktionelle materialer, materialer stakke og fuldstændige anordninger. Nanomoulding kombineret med lag transfer muliggør replikation af vilkårlige overflademønstre fra en master struktur på det funktionelle materiale. Nanomoulding kan udføres på enhver nanoimprinting opsætning og kan anvendes på et bredt udvalg af materialer og udfældningsprocesser. I særdeleshed har vi demonstrere fremstilling af mønstrede transparente zinkoxid elektroder til lette fældefangst ansøgninger i solceller.

<html> Figur 3 sammenfattes nogle illustrative eksempler på nanomoulded strukturer. En ZnO mester struktur dyrket ved CVD på glas er vist i (a). Den tilsvarende nanomoulded ZnO replika er vist i (d). Sammenligning af den lokale højde (g) og vinkel (j) histogrammer ekstraheret fra AFM billeder afslører high fidelity af nanomoulding processen. Tilsvarende resultater er vist for en endimensional gitter fremstillet af interferens litografi (b, e, h, k) og anodisk tekstureret aluminium (C, F, I, L). <...
