In order to compare simulation with experimental results, the static output characteristics on a long gate P-HFET have been measured over the temperature range 260-380 K. Hall mobility measurements at different temperatures and gate bias are included in the simulations. The static characteristics are simulated using a thermlonic field emission model that calculates the current across the Al0.3Ga0.7As/In0.3Ga0.7As heterojunction, where the effective band discontinuity is controlled by means of a parameter called effective length, l(ef). In this paper the use of l(ef) as a fitting parameter for the static characteristic curves is investigated.||URI:||http://hdl.handle.net/10553/46934||ISSN:||0268-1242||DOI:||10.1088/0268-1242/17/6/306||Source:||Semiconductor Science and Technology[ISSN 0268-1242],v. 17, p. 534-539|
