Moreover, by applying a transverse electric field to tri-layer graphene, we use TMF as a ballistic electron spectroscopy method to investigate controlled changes in the electronic …

WebThe photoluminescence (PL) of multiwalled carbon nanotubes (MWCNTs) synthesized with ethanol flames was investigated at temperatures from 30 to 300 K. Broad-band PL emission in the near-infrared region was observed at temperatures below 240 K. The PL intensity was abruptly boosted up at 240 K, and then quickly became quenched and undetectable as the …
