A novel effect of tunnel electron current induction (TECI) is theoreti
cally considered in n(+)-I-M structures with a penetrable potential ba
rrier (I-layer) resulting from heating the n(+)-layer electrons by an
external electric field and tunnelling them into the n(+)-layer throug
h the I-insulator. A tunnel electron current which is thus induced len
ds to charging the structure and to a potential difference - the tunne
l electromotive force (TEMF) - between the n(+)- and M-layers. TEMF is
a practically significant consequence of the TECI effect. An equation
for TEMF has been deduced using numerical calculations. Approximate a
nalytical solutions of this equation and their application limits ale
cited in electron temperature approximation as functions of the extern
al field, lattice temperature, and structure parameters. Calculations
of the TEMF build-up time are presented as functions of the external f
ield. All expressions are calculated for lattice temperatures of 300 a
nd 77 K. Experimental observation possibilities of TECI are also brief
ly viewed.
