Calculating the I-V characteristic of a single-electron diode

Square wells, quantum wells and ultra-thin metallic films

“…(solid, black), underestimated, and several results obtained by various authors remained unnoticed, and re-obtained in other forms; so, the domain has many repetitions and overlappings. For instance, in [19], the authors use the same method as that just exposed here in order to find a series expansion for the solutions of the eigenvalue equations, but the expansion used by them, equivalent to (65), is limited to second order terms. In fact, the precision of their research, which is focused on the physical properties of a mesoscopic film of thickness L z , does not request a better precision.…”

“…However, this precision is inferior to the precision of the Barker approximation which, as we could see, goes to third order terms. Apparently, it seems that in [19] Barker's results are ignored, and re-obtain the series using a different method.…”
