The dependence of Fowler-Nordheim current oscillations (FNCOs) on the twist angle between the facing Si layers in Si(111)/SiO2/Si(111) bonded structures is investigated. The observed systematic variation in oscillation amplitude with twist angle can be ascribed to transverse momentum conservation upon Fowler-Nordheim tunneling through thin SiO2. A calculation result; taking into account the twist-induced decrease in potential discontinuity and consequently in the reflection coefficient at the SiO 2/twisted Si interface; provides the theoretical basis for the experimental results. © 2006 The Japan Society of Applied Physics;
