Query: Radiation tolerance of two-dimensional material-based devices for space
  applications   Characteristic for devices based on two-dimensional materials are their low
size, weight and power requirements. This makes them advantageous for use in
space instrumentation, including photovoltaics, batteries, electronics, sensors
and light sources for long-distance quantum communication. Here, we present for
the first time a comprehensive study on combined radiation effects in earth's
atmosphere on various devices based on these nanomaterials. Using theoretical
modeling packages, we estimate relevant radiation levels and then expose
field-effect transistors, single-photon sources and monolayers as building
blocks for future electronics to gamma-rays, protons and electrons. The devices
show negligible change in performance after the irradiation, suggesting robust
suitability for space use. Under excessive $\gamma$-radiation, however,
monolayer WS$_2$ showed decreased defect densities, identified by an increase
in photoluminescence, carrier lifetime and a change in doping ratio
proportional to the photon flux. The underlying mechanism was traced back to
radiation-induced defect healing, wherein dissociated oxygen passivates sulfur
vacancies.
