Field induced hot-electron emission from quasi one-dimensional nanostructures of wide band gap semiconductors

In recent years, many experimental studies are reported on field electron emission from semiconductor nanostructures, but the related theoretical study is lacking behind. Thus, a number of important experimental observations are not physically explained; these include nonlinear plots on FN coordinates [1–4] and extremely large field enhancement factors (β
FN
) determined by fitting based FN theory [5–9].
