Thin film synthesis of SrZn2P2 with SrI2 post-annealing for enhanced crystallinity and optoelectronic quality
Sita Dugu, Shaham Quadir, Christopher P. Muzzillo +11
Ternary Zintl phosphides are promising light-absorbing semiconductors for thin-film optoelectronic applications, but strategies for controlling their microstructure and optoelectro…
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…
Interplay of Ferromagnetic and Antiferromagnetic Interactions in Epitaxial CoZnN
Sita Dugu, Sharad Mahatara, Corlyn E Regier +4
Antiperovskite nitrides with the general formula MN have attracted significant attention due to their tunable electronic and magnetic properties. Among them are many cobalt-bas…
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…
Low-Temperature Synthesis of Stable CaZnP Zintl Phosphide Thin Films as Candidate Top Absorbers
Shaham Quadir, Zhenkun Yuan, Guillermo Esparza +14
The development of tandem photovoltaics and photoelectrochemical solar cells requires new absorber materials with band gaps in the range of ~1.5-2.3 eV, for use in the top cell pai…
Thin Film Synthesis, Structural Analysis, and Magnetic Properties of Novel Ternary Transition Metal Nitride MnCoN2
Sita Dugu, Rebecca W Smaha, Shaham Quadir +8
