Abstract or Summary
  • Using a simple dry transfer process, I construct and characterize three nanoscale MoS2 devices using current-voltage curves, Raman spectroscopy, optical and atomic force microscopy. I compare these devices, the thinnest of which was few layer ( ≤ 10 nm) MoS₂ capable of showing photoconductance, with a current whose magnitude is affected by a split gate voltage. The thinnest device’s results show mechanical exfoliation paired with a dry transfer is an economical and effective way to fabricate ultrathin gate-tunable devices.
