Fundamental materials properties

  • The effects of dopant compensation (the simultaneous presence of p-type and n-type dopants) on carrier recombination and mobilities.
  • The relative impact of defects and impurities in n- and p-type silicon.
  • Fundamental properties of silicon such as Auger recombination, radiative recombination, and band-to-band absorption.
