Abstract

THz generation under excitation by ultrashort optical pulses in ordered arrays of GaAs nanowires is reported. It was found that the efficiency of THz radiation generation increases due to the resonant leaky mode excitation in nanowires. The maximum value of the THz field is achieved when the distance between the nanowires is of the order of the wavelength of exciting light.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The photo-Dember effect arising from unequal electron-hole diffusion rates is a common source of charge currents in nanowires, often in addition to or in competition with junction fields, depending on doping type.

    “The photo-Dember effect arising from unequal electron-hole diffusion rates is a common source of charge currents in nanowires31,222–224, often in addition to or in competition with junction fields221,222, depending on doping type.”
  • Greater-than-bulk THz emission efficiencies have been demonstrated in a variety of semiconductor nanowire systems including Si, GaAs, InAs, and InN, with improved light trapping in dense nanowire forests and resonant leaky modes in highly-ordered arrays increasing absorption and corresponding THz currents.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
