Carrier Generation and Recombination

534
Carrier generation is the process by which electron-hole pairs (EHPs) are created within the semiconductor. In direct-bandgap semiconductors, such as gallium arsenide (GaAs), this occurs efficiently when energy absorption prompts valence electrons to leap into the conduction band, leaving behind holes.
This process is given by the generation rate G and is efficient due to the conservation of momentum between the valence band maximum and conduction band minimum.
Indirect generation involves an...

Area of Science:

  • Ultrafast spectroscopy
  • Quantum materials science
  • Solid-state physics

Background:

  • Solid-state high harmonic generation (sHHG) spectroscopy is a powerful technique for probing electronic structure and crystal symmetries in materials.
  • Substrate-supported samples are commonly used, with the assumption that substrates do not contribute significantly to the sHHG signal.
  • This assumption may not hold, as substrates can emit sHHG signals, potentially interfering with the analysis of the target material.

Purpose of the Study:

  • To investigate and characterize the sHHG emissions from commonly used optical substrates.
  • To evaluate the influence of substrate properties (e.g., crystalline quality, orientation) on sHHG.
  • To provide guidance for selecting appropriate substrates to minimize interference in sHHG studies of novel quantum materials.

Main Methods:

  • Power-dependent and polarization angle-resolved sHHG measurements were performed.
  • Fused silica, calcium fluoride, diamond, and sapphire substrates were studied.
  • A mid-infrared (MIR) driving field was used for sHHG excitation.

Main Results:

  • Substrate sHHG emissions were observed at moderate driving field intensities.
  • The sHHG yield and angular dependence of substrates vary significantly.
  • Different crystalline qualities and orientations of the same substrate material exhibit distinct sHHG characteristics.

Conclusions:

  • Substrate contributions to sHHG must be carefully considered, especially at higher driving field intensities.
  • Optimal substrate selection is crucial for accurate interpretation of sHHG data from novel materials.
  • This work facilitates the study of a broader range of materials by minimizing substrate-related artifacts.
