Course content

Introduksjon til nanoteknologi og arbeid i nanoskala. Definisjoner, typiske fenomener og lover. Innsikt og eksempler fra nanomaterialer, bionanoteknologi, nanofysikk og nanomedisin.

Introduksjon til materialvitenskap og teknologi. Metaller, polymerer, keramer, glass og karbonmaterialer, struktur og egenskaper. Bærekraft innen nanoteknologi og materialteknologi.

Atomstruktur og interatomære bindinger. Struktur av krystallinske faste stoffer. Defekter og dislokasjoner.

Nanofabrikasjon, enkel litografi.

Mekaniske egenskaper, elastisk og plastisk deformasjon. Hvordan mekaniske egenskaper kan konstrueres ved hjelp av ytre påvirkninger (temperatur, lys, herding) og brukes til nanoapplikasjoner.

Eksperimentelle teknikker: SEM (teoretisk) og AFM (praktisk).

Dette emnet er en del av ingeniørstigen i Nanoteknologi.

Learning outcome

Knowledge:

After completing the course the student should be able to:

- Define and reflect on the limits and possibilities of nanotechnology as a research and development field

- Discuss the connections between nanoscience and the traditional disciplines like physics, chemistry, biology and material science

- Explain life cycles of materials, especially with emphasis on recycling in a sustainable society and complexity of nanodevices.

- Explain how the properties of the materials are linked to chemical composition, atomic structure and microstructure

- Explain the most basic facts about the most commonly used metals and their alloys, ceramics and polymers, and how the properties are connected to chemistry and structure and size.

- Describe mechanical properties and how they are affected by defects and dislocations during elastic and plastic deformation. The difference of macroscale and nanoscale.

- Explain the underlying mechanisms of lithography and the difference of structures at the macroscale vs nanoscale.

Skills:

- Use scaling laws to predict the properties of nanoscale materials.

- Calculate characteristics of simple crystal structures.

- Comparisons of materials for use in different applications. Decide criteria for comparisons and prioritations (ex price, sustainability, properties). Find relevant data in tables, sketch relevant data in graphs and program simple procedures. Argue orally and in writing for material choices.

- Perform simple lithography steps, using spin-coater, physical masks and development

- Perform simple topography characterization and mechanical force of macroscopic structures using Atomic Force Microscopy

- Use programming to make masks for lithography

- Create functional lab journals
