The in-plane magnetotransport of detwinned EuFe2As2 single crystal has been investigated.In the antiferromagnetic phase of Eu^2+spins,very different magnetoresi
The electrocaloric effect of ferroelectric ceramics has been studied extensively for solid-state caloric cooling.Generally,most ferroelectric ceramics are poor
The graded AlGaN:Si back barrier can form the majority of three-dimensional electron gases(3DEGs)at the GaN/graded AlGaN:Si heterostructure and create a composi
