Advanced Piezoelectric Crystals for Acoustoelectronics

open access: diamondJournal of Physics: Conference Series, 2023
Abstract Ferroelectric crystals of LiNb(1-x)TaxO3 solid solutions and piezoelectric crystals Ca3TaGa3Si2O14 were grown by the Czochralski method. The composition of LiNb(1-x)TaxO3 crystals was studied by mass spectrometry with inductively coupled plasma.

Acoustoelectronic nanotweezers enable dynamic and large-scale control of nanomaterials [PDF]

open access: goldNature Communications, 2021
AbstractThe ability to precisely manipulate nano-objects on a large scale can enable the fabrication of materials and devices with tunable optical, electromagnetic, and mechanical properties. However, the dynamic, parallel manipulation of nanoscale colloids and materials remains a significant challenge.

The piezoelectric semiconductor and acoustoelectronic device development in the sixties

open access: greenIEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004
In the 1960s the properties of piezoelectric semiconductors, group III-V zinc-blende and group II-VI wurtzite structure, were explored for the development of acoustoelectronic (AE), devices. Bulk acoustic wave (BAW), delay lines, traveling wave amplifiers, and oscillators were developed.
