Abstract: Lead-free relaxor ferroelectrics are promising candidates for next-generation piezoelectric high-power devices, such as ultrasonic motors, transformers, and therapeutic ultrasonics. These applications require hard ferroelectrics with a broad operating temperature range. Recently, acceptor Zn2+ doping and… read more here.

DOI: 10.1134/s1063785017060232
Abstract: We propose a backward-diode heterostructure modified by a built-in acceptor-doped layer that forms an additional potential barrier decreasing the transverse transport of hot electrons to the substrate. According to calculations, this structure is characterized by… read more here.
