Setup explanation:

  • External Quantum Efficiency (EQE) Consists on a custom-built setup.
  • Light source: a stabilized xenon lamp or supercontinuum LASER. 
  • Monochromator (Horiba microHR). 1nm spectral resolution.
  • A beamsplitter (Thorlabs BPD254-G) allows for the excitation light to simultaneously illuminate the sample and a photodiode connected to a power meter (Thorlabs S120VC & PM100A).
  • Current is acquired using a multimeter (Keithley 2400 SourceMeter).
