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…

Scaling in large area field emitters and the emission dimension

Rashbihari Rudra, Debabrata Biswas

Electrostatic shielding is an important consideration for large area field emitters (LAFE) and results in a distribution of field enhancement factors even when the constituent emit…

Verification of shielding effect predictions for large area field emitters

Rashbihari Rudra, Debabrata Biswas

A recent analytical model for large area field emitters, based on the line charge model (LCM), provides a simple approximate formula for the field enhancement on hemi-ellipsoidal e…

Electrostatic shielding versus anode-proximity effect in large area field emitters

Debabrata Biswas, Rashbihari Rudra

Field emisison of electrons crucially depends on the enhancement of the local electric field around nanotips. The enhancement is maximum when individual emitter-tips are well separ…

Shielding effects in random large area field emitters, the field enhancement factor distribution and current calculation

Debabrata Biswas, Rashbihari Rudra

A finite-size uniform random distribution of vertically aligned field emitters on a planar surface is studied under the assumption that the asymptotic field is uniform and parallel…
