Graphene and its derivatives are expected to be efficient field emitters due to their unique geometry and electrical properties. In this work we have decorated Graphene nanosheets with noble metal nanoparticles specifically Platinum by simple chemical route which produces high density of protrusions. The assynthesized Graphene nanosheets were characterized using XRD and TEM. The values of turn-on...
Due to high monetary turnover in business, white pigeon keeping for game purposes is gaining more popularity in Punjab. Overcrowding and poor management by undertrained naive farmers make these birds more susceptible to diseases not known so far in this region. A farmer reported that about a hundred pigeons were unable to feed properly and regurgitate feed. Birds lost body condition gradually, and...
Herein we report, pressure dependent field emission (FE) behaviour of a few-layer graphene emitter. Gas dependent FE properties have been investigated in ultra high vacuum (UHV), as well as in N2 and O2 ambience at base pressure ∼ 1×10−6 torr. Interestingly, the graphene emitter when operated in N2/O2 ambience exhibits lower turn-on field and higher emission current density, as compared to the UHV...
