Valid for year : 2008
 
TNE063 Charge Transport in Organic and Inorganic Materials, 6 ECTS credits.
/Laddningstransport i organiska och oorganiska material/

For:   ED   MES  

 

Prel. scheduled hours:
Rec. self-study hours: 160

  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 Devices, 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: electron transfer theory, vibrations in molecules and solids, Schrödinger equation for periodical potential, energy bands, Fermi golden rule, and diffusion mechanism.
  • Transport in crystalline materials: Boltzmannâ?Ts transport equation: derivation, conditions of validity and several solutions: relaxation time and Monte-Carlo simulation.
  • Transport in disordered materials: localized and delocalized states, traps, hopping, polarons and bipolarons.
  • Ionic transport in organic material: diffusion and migration currents. Chemical and structural issues for ionic transport.
Course literature:
To be decided
Examination:
Written examination
Computer simulations
 5 ECTS
1 ECTS
