Semiconductor Probes of Light Dark Matter

Graham, Peter W., Kaplan, David E., Rajendran, Surjeet et al.

Understand

Dark matter with mass below about a GeV is essentially unobservable in conventional direct detection experiments.

  • However, newly proposed technology will allow the detection of single electron events in semiconductor materials with significantly lowered thresholds.
  • This would allow detection of dark matter as light as an MeV in mass.
  • Compared to other detection technologies, semiconductors allow enhanced sensitivity because of their low ionization energy around an eV.
