Fast and accurate determination of the curvature-corrected field emission current
Debabrata Biswas, Rajasree Ramachandran
The curvature-corrected field emission current density, obtained by linearizing at or below the Fermi energy, is investigated. Two special cases, corresponding to the peak of the n…
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…
Interpreting the empirical field emission equation for large area field emitters
Debabrata Biswas
Both single emitters and large area field emitters (LAFE) are generally characterized using the slope and intercept of a Murphy-Good (or Fowler-Nordheim) plot which are used to ext…
Gamow factors and current densities in cold field emission theory: a comparative study
Debabrata Biswas
The factors that contribute to the accuracy of the cold field emission current within the contemporary frameworks are investigated. It is found that so long as the net current is e…
Predicting space-charge affected field emission current from curved tips
Debabrata Biswas, Raghwendra Kumar, Gaurav Singh
Field emission studies incorporating the effect of space charge reveal that for planar emitters, the steady-state field , after initial transients, settles down to a value low…
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…
