The anode proximity effect for generic smooth field emitters

Debabrata Biswas

The proximity of the anode to a curved field electron emitter alters the electric field at the apex and its neighbourhood. A formula for the apex field enhancement factor, …

The cosine law of field enhancement factor variation: generic emitter shapes

Debabrata Biswas, Gaurav Singh, Rajasree Ramachandran

The cosine law of field enhancement factor variation was recently derived for a hemi-ellipsoidal emitter and numerically established for other smooth emitter shapes (Biswas et al,…

Curvature correction to the field emission current

Debabrata Biswas, Rajasree Ramachandran

The curvature of field emitter tips leads to an altered tunneling potential that assumes significance when the radius of curvature is small. We provide here an analytical curvature…

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…

A universal formula for the field enhancement factor

Debabrata Biswas

The field enhancement factor (FEF) is an important quantity in field emission calculations since the tunneling electron current depends very sensitively on its magnitude. The exact…

Field-emission from parabolic tips: current distributions, the net current and effective emission area

Debabrata Biswas

Field emission from nano-structured emitters primarily takes place from the tips. Using recent results on the variation of enhancement factor around the apex (Biswas et al, Ultrami…
