Alloying to Tune the Bandgap of the AM2Pn2 Zintl Compounds
Andrew Pike, Zhenkun Yuan, Muhammad Rubaiat Hasan +6
The AM2Pn2 Zintl compounds are a large class of semiconductor materials that have a wide range of bandgaps and are mostly stable in the same crystal structure. Representative compo…
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…
Ge0.95Sn0.05 on Si avalanche photodiode with Spectral Response Cutoff at 2.14 micrometer
Justin Rudie, Xiaoxin Wang, Rajesh Kumar +9
GeSn-based avalanche photodiode (APD) operating in shortwave infrared (SWIR) wavelength was demonstrated in this work. A separate absorption and charge multiplication (SACM) struct…
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.…
Semiconductor-compatible topological digital alloys
Yunfan Liang, Damien West, Shunda Chen +3
Recently, GeSn alloys have attracted much interest for direct-gap infrared photonics and as potential topological materials which are compatible with the semiconductor industry. Ho…
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…
