Large Piezoelectric Response of van der Waals Layered Solids

29 Apr 2018 Manna Sukriti Gorai Prashun Brennecka Geoff L. Ciobanu Cristian V. Stevanović Vladan

The bulk piezoelectric response, as measured by the piezoelectric modulus tensor (\textbf{d}), is determined by a combination of charge redistribution due to strain and the amount of strain produced by the application of stress (stiffness). Motivated by the notion that less stiff materials could exhibit large piezoelectric responses, herein we investigate the piezoelectric modulus of van der Waals-bonded quasi-2D ionic compounds using first-principles calculations...
