Under the optimized pulsed laser deposition (PLD), a well-adhered coating of GdB6 nanoparticles on chemically synthesized cuprous oxide (Cu2O) nanoneedles has been obtained. A plausible growth mechanism of the hierarchical assembly of GdB6 nanoparticles on the Cu2O nanoneedles is explained on the basis of structural analysis carried out using SEM and TEM. A low turn-on field of similar to 2.3 V mu m(-1) (to draw an emission current density similar to 1 mu A cm(-2)) is observed along with stable emission current at the preset value of similar to 2 mu A over 4 h. The enhanced emission behaviour of the GdB6/Cu2O heteroarchitecture, in contrast to the pristine Cu2O nanoneedles, is attributed to its high aspect ratio and low work function. The observed FE results demonstrate GdB6/Cu2O heteroarchitecture as a potential candidate for application in various vacuum nano/microelectronic devices.</p>1 aSuryawanshi, Sachin, R.1 aSingh, Anil, K.1 aDeo, Meenal, S.1 aLate, Dattatray, J.1 aSinha, Sucharita1 aMore, Mahendra, A.  uhttps://library.ncl.res.in/content/3d-hetero-architecture-gdb6-nanoparticles-lessened-cubic-cu2o-nanowires-enhanced-field-0
