The morphological and structural analyses of the as-deposited single-layer MoSe2 nanosheets were carried out using an optical microscopy, Raman spectroscopy and atomic force microscopy. Furthermore, the values of turn-on and threshold fields required to extract an emission current densities of 1 and 10 mu A cm(-2), are found to be similar to 1.9 and similar to 2.3 V mu m(-1), respectively. Interestingly, the MoSe2 nanosheet emitter delivers maximum field emission current density of similar to 1.5 mA cm(-2) at a relatively lower applied electric field of similar to 3.9 V mu m(-1). The long term operational current stability recorded at the preset values of 35 mu A over 3 hr duration and is found to be very good. The observed results demonstrates that the layered MoSe2 nanosheet based field emitter can open up many opportunities for their potential application as an electron source in flat panel display, transmission electron microscope, and x-ray generation. Thus, the facile one step synthesis approach and robust nature of single-layer MoSe2 nanosheets emitter can provide prospects for the future development of practical electron sources.</p>10aatomically thin nanosheets10achemical vapor deposition10afield emission10alayered MoSe21 aSuryawanshi, Sachin, R.1 aPawbake, Amit, S.1 aPawar, Mahendra, S.1 aJadkar, Sandesh, R.1 aMore, Mahendra, A.1 aLate, Dattatray, J.  uhttps://library.ncl.res.in/content/enhanced-field-emission-behavior-layered-mose2
