• Be able to explain all equations in equation booklet.
    • Variables, where to use them, constraints
  • Exam content will be more similar to problem sheets then tutorial problems
  • May be crossovers between different parts (Ferroelectrics/Perovskites, etc )
  • There will be three questions, each one will have a main theme
    • OSC
    • Ferroelectrics
    • Nanomaterials
    • Laundau
  • Take a look at tutorial sheets again

Mock Exam Review

  • Structure should be same as previous exam
  • One of the question isn’t involved (liquid crystals)
  • Ratio of triplet/singlets (25%) seems likely to be on test
  • The content may be different, but marking scheme should be similar
  • Graph analysis?
    • Characterisitc curves of different devices
    • Photoelectric cells?

Tips

  • Time it properly, practice your timing
  • Make sure that you use the correct terms and jargon
    • Dirac cone, Pauli blocking, etc etc

Bonus tips

  • This is first year with perovskites and quantum dots. So there will be question on perovskites and quantum dots
  • Good examples in tutorial sheets and problem sheets
  • 3d and 2d perovskites
  • ion intermixing
  • bandgap tuning
  • 2d perovskites
    • Mix 2 topics, nano-materials and perovskites
    • Calculate band shift in perovskites
    • Analyze property shift between 2d and 3d
  • Easily expect question on OSC. At least 1 questions
    • May be questions on specific devices
    • Advantage/Disadvantage
    • Explain how structure/composition effects properties
    • twist of backbone, alkyl chains
    • knowing the different architectures
    • OFETS
    • Sketch them, name components
    • Name differences and what they are good for
    • Analyze graphs, extract efficiencies and etc
  • What kind of semiconductor? p type, n type
  • Differentiate between linear and saturation regimes
  • Approximating mobility in linear and saturation regimes
  • What actually happens in real device? “Is this reasonable” type questions

Nanomaterials

  • different confinements
  • Quantum dots absorption reflection
  • being able to calculate quantum dot size
