Monolithic Piezoelectric Sensor for Measurement of Triaxial Forces Applied to Bridge by String Vibration

Abstract

A new two-dimensional map is proposed to investigate the nonlinear and quantum effects on the tunnelling of carriers (electrons or holes) in a novel one-dimensional semimagnetic semiconductor superlattice. The magnetic-polaron effect resulting from the exchange interaction between the carrier in a mesoscopic dot and localized magnetic-ion spins leads to a nonlinear nature of the effective Schrödinger equation for the carrier. We find gaps and different multistability in the tunnelling properties of carriers that depend critically on the wavevector of the injected carriers. In particular, when the nonlinear coefficient is increased new nontunnelling regions appear adjacent to the regular instability regions. The properties can be useful for the transmission of information in microelectronic devices.
