Such a heterojunction with the junction area in the nanoscale displays enhanced field emission characteristics at low turn-on field, with a nearly three times increase in the field enhancement factor.</p>1 aKale, Vinayak, S.1 aSathe, Bhaskar, R.1 aKushwaha, Ajay1 aAslam, Mohammed1 aShelke, Manjusha, V.  uhttps://library.ncl.res.in/content/novel-catalyst-free-synthesis-vertically-aligned-silicon-nanowire-carbon-nanotube-0
