Glassy thermal transport and zT of 2.7 in doped GeTe results from the inhomogeneous ferroelectric instability developed due to local polar distortions near the dopant sites. Just out in Advanced Materials Debattam Sarkar Subarna Das JNCASR Bangalore advanced.onlinelibrary.wiley.com/doi/10.1002/ad…

We report a 3D perovskitoid iodide with a direct 2.0 eV bandgap by increasing the fraction of corner-sharing octahedra in its structure. It exhibits enhanced light stability compared to mixed-halide perovskites and makes a novel solar cell. pubs.acs.org/doi/abs/10.102…

New in JACS! Chiral hybrid lead halides templated by L-nicotinium form distinct 1D & 0D motifs, exhibiting broadband emission and polarized light emission. Their optical activity is directly linked to the chiral organic cation and halide sublattice. pubs.acs.org/doi/abs/10.102…

Our next JACS... While eCO2RR in alkaline media enables selective CO2 conversion, carbonate formation limits commercialization. Our perspective explores how acidic conditions can overcome this barrier, advancing efficient and scalable CO2 reduction. pubs.acs.org/doi/10.1021/ja…

Great to have you on board Jesse!

SnP₂Se₆, a 2D van der Waals chiral semiconductor, with bandgap ~1.47 eV and a large non-resonant SHG coefficient of d₃₃ ≈ -222 pm/V, about 7× larger than AgGaSe₂. It supports both Type-I and Type-II phase matching over a wide spectral range advanced.onlinelibrary.wiley.com/doi/full/10.10…

Angew Chemie: PbSnS₂ a low-cost thermoelectric material with halogen doping (Cl, Br, I) can boost carrier concentration, activate multiband transport, and suppress thermal conductivity leading to ZT = 0.82 at 873 K and an ultralow κ_lat of 0.29 W/mK. onlinelibrary.wiley.com/doi/10.1002/an…

The Kanatzidis Symposium at the ACS Meeting in San Diego marked the close of a beautiful two-day event. I was deeply honored and touched by the generosity and thoughtfulness of former alumni, friends, and colleagues who made it all happen.

Just published..2 alkali chalcopnictates RbSbP₂S₆ & β-RbBiP₂S₆ chain-like, semiconducting, and subtly different in metal coordination. β-phase Bi beats α in synthesis ease, but not in SHG. RbSbP₂S₆ more resistant to lasers. pubs.acs.org/doi/abs/10.102…

New in Chemical Reviews: How to make Te-free thermoelectrics efficient and stable. From band convergence to entropy and interface engineering, we map the latest strategies for turning waste heat into power—without rare elements. #thermoelectrics pubs.acs.org/doi/abs/10.102…

Congratulations Jesse!

Joint student Yukun Liu (Dravid/Kanatzidis) brilliantly defended his thesis today! Wolverton, Snyder as cmte members. He did outstanding work on high entropy alloy semiconductors: deep, fundamental science. Next stop: Lam Research, Oregon. Wishing him great success!

Lidong Zhao introduced the term synglisis (from the Greek σύγκλισις for convergence) to describe the progressive merging of distinct electronic bands, initially converging in energy and subsequently in momentum space, typically under external perturbations science.org/doi/10.1126/sc…

Just had a fantastic visit at the University of Rennes with collaborators Jacky Even, Mika Kepenekian, and Claudine Katan, George Volonakis leaders of a world-class materials theory group pushing the frontiers of perovskites and beyond. Inspiring science and great discussions!

New in JACS: Structural & band modulation in perovskite-inspired semiconductors. We uncover Pb:Sn ratio–driven polytypism in perovskitoids (APb₁₋ₓSnₓI₃): 3 polytypes (9R, 12R, 6H), Bandgap tunable: 2.51 → 1.87 eV and stable photoresponse in devices pubs.acs.org/doi/10.1021/ja…

Perovskite g-ray detectors aren’t just for hole collection anymore. We show high-quality CsPbBr₃ can achieve high g-ray resolution via electron collection. Electrons work, if you grow it right. #Perovskites #RadiationDetection #MaterialsScience, pubs.acs.org/doi/abs/10.102…

We unveil a full series of AnCu4-nTiS₄ semiconductors with evolving 3D → 0D dimensionality by stepwise Cu→A substitution. This drives rational changes in structure, band gap, PL, and stability, highlighting design rules for property tuning. #JACS pubs.acs.org/doi/abs/10.102…
