Emergent Random Spin Singlets in Disordered Spin-1/2 perovskite BaCuTaO
Sagar Mahapatra, Francesco De Angelis, Dibyata Rout +8
We investigate the disordered perovskite BaCuTaO, where Cu (spin-1/2) and Ta randomly occupy a pseudo-cubic lattice. Synchrotron X-ray diffraction and X-ray abs…

Scalable solution chemical synthesis and comprehensive analysis of Bi2Te3 and Sb2Te3
Bejan Hamawandi, Parva Parsa, Inga Pudza +7
Thermoelectric (TE) materials can directly convert heat into electrical energy. However, they sustain costly production procedures and batch-to-batch performance variations. Theref…
