Valid for year : 2007
 
TNE078 Charge Transport in Organic and Inorganic Materials, 7,5 ECTS credits.
/Laddningstransport i organiska och oorganiska material/

For:   ED   MES  

 

Prel. scheduled hours:
Rec. self-study hours: 200

  Area of Education: Sciences

Subject area: Physics
  Advancement level (G1, G2, A): A

Aim:
This course gives the students the basics in theory of charge transport in inorganic and organic materials necessary to tackle more advanced courses in inorganic and organic semiconductor devices. To succeed the course, the students are expected to be able to:
  • use the knowledge in modern physics, molecular physics, and mathematics
  • explain various concepts involved in charge transport (conductivity and mobility, electrons and holes, effective mass, polarons and ions, migration and diffusion, rate of electron transfer and hopping, influence of disorder, band structure and band width)
  • calculate with the help of models, the charge conduction properties in inorganic and organic materials


Prerequisites: (valid for students admitted to programmes within which the course is offered)
Modern Physics, Molecular Physics, Semiconductor Technology, Organic Electronics or equivalent courses.

Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding.
Organisation:
The course contains lectures, tutorials and computer-based laboratory work.
Course contents:
  • Basic quantum mechanics and solid state physics: Schrödinger equation for periodic potential, energy band, density of states, Fermiâ?Ts golden rule, scattering mechanisms. Su, Shrieffer and Heeger (SSH) Hamiltonian
  • Transport in crystalline materials: Boltzmannâ?Ts transport equation: derivation, applicability and some solutions/approximations: Relaxation time, balance equations and Monte-Carlo simulations.
  • Transport in disordered inorganic and organic materials: Localized-delocalized states. Mott- and Anderson transitions, traps, "hopping", solitons, polarons and bipolarons.
  • Ion transport in organic materials: diffusion and ionic current. Chemical and structural aspects on ion transport.
  • Modeling of practical applications: transistors and ion pumps.
