Quantitative correlation between structural (dis-)order and diffuseness of phase transition in lead scandium tantalate
T. Granzow, A. Aravindhan, Y. Nouchokgwe +9
Ferroelectrics show a phase transition to a paraelectric phase at a well-defined transition temperature. Introducing disorder makes this transition diffuse, and the system becomes…
Sub-micron Cu(In,Ga)Se2 solar cell with efficiency of 18.2% enabled by a hole transport layer
Taowen Wang, Longfei Song, Saeed Bayat +6
Reducing the thickness of Cu(In,Ga)Se2 solar cells is a key objective in order to reduce production cost and to improve sustainability. The major challenge for sub-micron Cu(In,Ga)…
Solution-Based Fabrication of High-Performance KNaNbO Thin Films for Surface Haptics
Nagamalleswara Rao Alluri, Longfei Song, Stephanie Girod +8
KNaNbO is among the most promising lead-free piezoelectrics. While its sputtered films match the performance of the champion piezoelectric Pb(Zr,Ti)O, repro…
Tunable electrocaloric effect in lead scandium tantalate through calcium doping
Youri Nouchokgwe, Natalya S. Fedorova, Pranab Biswas +11
State-of-the-art electrocaloric cooling prototypes rely on the conventional electrocaloric effect of ferroelectric lead scandium tantalate (PbSc0.5Ta0.5O3, PST), which peaks near r…
