Long photoexcited carrier lifetime in a stable and earth-abundant zinc polyphosphide
Zhenkun Yuan, Genevieve Amobi, Shaham Quadir +16
Halide perovskites have revolutionized optoelectronics by demonstrating that long carrier lifetime can be achieved in materials processed in relatively uncontrolled environments, w…
CaCdP: A Visible-Light Absorbing Zintl Phosphide Stable under Photoelectrochemical Water Oxidation
Guillermo L. Esparza, Zhenkun Yuan, Muhammad Rubaiat Hasan +9
A key bottleneck to solar fuels is the absence of stable and strongly absorbing photoelectrode materials for the oxygen evolution reaction (OER). Modern approaches generally trade…
BaCd2P2: a promising impurity-tolerant counterpart of GaAs for photovoltaics
Gideon Kassa, Zhenkun Yuan, Muhammad R. Hasan +5
BaCd2P2 (BCP) has been recently identified as a new solar absorber with promising optoelectronic properties. This work demonstrates that, despite having a low precursor purity (98.…
A Map of the Zintl AM2Pn2 Compounds: Influence of Chemistry on Stability and Electronic Structure
Andrew Pike, Zhenkun Yuan, Gideon Kassa +9
The AM2Pn2 (A= Ca, Sr, Ba, Yb, Mg; M= Mn, Zn, Cd, Mg; and Pn=N, P, As, Sb, Bi) family of Zintl phases has been known as thermoelectric materials and has recently gained much attent…
