Semi-analytical theory of emission and transport in a LAFE-based diode
Debabrata Biswas, Rashbihari Rudra, Raghwendra Kumar
A large area field emitter (LAFE) typically consists of several thousands of nanoscale emitting tips. These are difficult to simulate using purely numerical methods based on finite…
Approximate universality in the electric field variation on a field-emitter tip in the presence of space charge
Raghwendra Kumar, Gaurav Singh, Debabrata Biswas
The electric field at the surface of a curved emitter is necessary to calculate the field emission current. For smooth parabolic emitting tips where space charge is negligible, var…
Simulating multiscale gated field emitters -- a hybrid approach
Shreya Sarkar, Raghwendra Kumar, Gaurav Singh +1
Multi-stage cathodes are promising candidates for field emission due to the multiplicative effect in local field predicted by the Schottky conjecture and its recent corrected count…
Variation of field enhancement factor near the emitter tip
Debabrata Biswas, Gaurav Singh, Shreya G. Sarkar +1
The field enhancement factor at the emitter tip and its variation in a close neighbourhood determines the emitter current in a Fowler-Nordheim like formulation. For an axially symm…
