Summary: This study successfully fabricated PbZrO3 (PZO) films on a LaNiO3 (LNO)-buffered Si(100) substrate using a sol-gel spin-coating technique, and demonstrated excellent bipolar resistance switching (RS) behavior in the resulting Au/PZO/LNO/Si heterojunction device. The device showed a high/low resistance ratio of 10^2 at bias voltages of +0.2 and -0.2 V, with RS characteristics remaining stable after 100 consecutive cycles of testing. Weibull distribution analysis indicated a uniform and stable high/low-resistance state, and conduction mechanisms were identified as Ohmic conduction and Schottky emission, with the RS phenomenon attributed to modulation of a Schottky-like barrier due to oxygen vacancy migration in the PZO films.

Summary: This study investigates the AlN nucleation layer issue in GaN high frequency telecommunication and power switching systems fabricated after heteroepitaxy on Silicon or Silicon Carbide. It is shown that using 3C-SiC as an intermediate layer can significantly decrease RF propagation losses. Measurements and analyses demonstrate that dopant diffusion into the 3C-SiC pseudo-substrate is confined beneath the interface, and a slightly conductive zone is present beneath the AlN/3C-SiC interface, explaining the low propagation losses obtained for the devices. This work highlights the importance and efficiency of the 3C-SiC intermediate layer as a pseudo-substrate.
