“…Recently, we have been reported the enhance field emission behaviour of the GdB 6 ‐Cu 2 O and GdB 6 ‐ZnO heteroarchitecture assembly via facile synthesis route . Also the Silicon nanotubes coated on W‐tip was used as a field emitter, which showed quite high field enhancement factor . Furthermore, for a flat multi‐tip emitter and heteroarchitecture system where the assembly of a large number of nanostructures deposited in thin film form on suitable substrate are observed to be very reliable for to obtain the enhance FE characteristics.…”

Herein, we report the one step arc plasma synthesis of the GdB6 (Gadolinium hexaboride) nanoparticles and its field emission (FE) characteristics on tungsten point substrate (GdB6/W). The SEM / TEM analysis revealed the GdB6 nanoparticles on W point substrate exhibit irregular shaped, grainy, dense, course morphology, i. e. uniformly covering the entire tip substrate surface. For GdB6/W point source, the values of the turn‐on and threshold fields, defined as field required to draw an emission current density ∼1 mA/cm2 and ∼100 mA/cm2, respectively are found to be ∼ 2.2 and ∼2.7 V/μm, for anode‐cathode separation of ∼1 mm. Interestingly, a very high emission current density of ∼3.5 A/cm2 has been drawn from the GdB6/W point emitter at relatively lower applied field of ∼6.4 V/μm. The field enhancement factor found to be ∼10,250. The GdB6/W point electron source exhibits a good emission current stability at ∼10 mA for a period of 6 hr. The emission current stability is enumerated in terms of standard deviation and its magnitude has been measured to be only 1.72 % with respect to the average value. The superlative field emission characteristics signify the GdB6/W point electron source as potential candidates for vacuum micro/nanoelectronics device applications.

Herein we report field emission (FE) investigations on an electrochemically exfoliated few-layered black phosphorus nanosheet emitter at a base pressure of approximately 1 ϫ 10 -8 mbar. The turn-on electric field required to draw an emission current density of approximately 10 μA/cm 2 is found to be about 4.2 V/μm. Furthermore, few-layered black phosphorus nanosheet emitters deliver an emission current density of about 170 μA/cm 2 at an applied field of about 7.5 V/ CSIR-

The graphene and semiconducting hybrid based nanostructures have emerged as a new class of multifunctional materials with improved performance in comparison to the pristine semiconductors. Here, as-synthesized MoO 3 -reduced graphene oxide (rGO) nanocomposite emitter exhibits enhanced field emission (FE) behavior as compared to the pristine 1D MoO 3 nanorods. The hydrothermally synthesized 1D MoO 3 nanorods (1D) are grafted on the rGO sheet (2D) using a simple room temperature sonochemical method. The morphological and structural analysis confirms the attachment of MoO 3 nanorods with rGO and the improved conductivity of the sample indicates a strong electronic interaction between them. Furthermore, the FE studies of as-synthesized MoO 3 nanorods and MoO 3 -rGO nanocomposite emitters, carried out at a base pressure~1 3 10 À8 mbar, reveals the values of turn on field (required to draw an emission current density of 1 mA/cm 2 ) as 1.6 and 1.4 V/mm, respectively. Interestingly, the maximum emission current density of 2810 mA/cm 2 is achieved at a lower applied field of 2.7 V/mm from the MoO 3 -rGO nanocomposite emitter. The enhancement in FE performance of MoO 3 -rGO nanocomposite is attributed to the improved electrical conductivity, mechanical properties and higher concentration of protruding edges (emission sites). This observation can be extended to other graphene-based 1D inorganic hybrid semiconductor nanocomposites, which can provide a valuable opportunity to explore novel hybrid materials for vacuum nano-electronic devices.
