Structural, electronic, vibrational, optical, piezoelectric, thermal and thermoelectric properties of BCZT from first-principles calculations

Debidutta Pradhan, Jagadish Kumar

Perovskite material such as BCZT (Ba $_{0.875}$ Ca $_{0.125}$ (Zr $_{0.125}$ Ti $_{0.875}$ )O $_{3}$ ) is well known for its high value of piezoceramic properties and Curie temperature which…

Correlation between stick-slip frictional sliding and charge transfer

G. Ananthakrishna, Jagadish Kumar

A decade ago, Budakian and Putterman (Phys. Rev. Lett., {\bf 85}, 1000 (2000)) ascribed friction to the formation of bonds arising from contact charging when a gold tip of a surfac…
