Phase evolution and enhanced room temperature piezoelectric properties response of lead-free Ru doped BaTiO3 ceramic
Kumar Brajesh, Sudhir Ranjan, Ashish Garg
Recent years have witnessed considerable work on the development of lead-free piezoelectric ceramic materials and their structure-property correlations. The development of piezo re…
Room Temperature Structural, Magnetic and Dielectric Characteristics of La Doped CuO Bulk Multiferroic
Kumar Brajesh, Sudhir Ranjan, Rajeev Gupta +2
In this manuscript, we report room temperature structural, microstructural, optical, dielectric, and magnetic properties of CuO and Cu0.995La0.005 ceramics, synthesized by solid-st…
Low temperature magnetic and dielectric properties correlation in Fe-doped copper (ii) oxide ceramics for potential device application
Kumar Brajesh, Ritamay Bhunia, Shashikant Gupta +3
The bulk samples of CuO and Fe-doped CuO were synthesized by ceramics methods. Structural and compositional analyses were performed by using X-ray diffraction, SEM, and EDAX. Throu…
High Pressure Structural Investigation on Lead-Free Piezoelectric -
Anshuman Mondal, Pinku Saha, Bishnupada Ghosh +4
The solid solution - (BCZT) has become a promising member of the lead-free piezoelectric materials because of its exceptiona…
Correlation between structure and Rayleigh parameters in the lead-free piezoceramic (1-x)Ba(Ti0.88 Sn0.12)O3-x(Ba0.7Ca0.3)TiO3
Mulualem Abebe, Kumar Brajesh, Rajeev Ranjan
Composition dependent Rayleigh and structural analysis was carried out on the lead-free piezoceramics (1-x)(BaTi0.88Sn0.12)-x(Ba0.7Ca0.3)TiO3 at room temperature. The system exhibi…
A structural perspective on the origin of the anomalous weak-field piezoelectric response at the polymorphic phase boundaries of (Ba, Ca)(Ti, M)O3 lead-free piezoelectrics
Mulualem Abebe, Kumar Brajesh, Anupam Mishra +2
In this paper, we compare the structural features of Ca modified Ba(Ti, Sn)O3 with that of its Ca-free counterpart to understand why the Ca-modified variant of this lead-free piezo…
