Scalable synthesis of 2D van der Waals superlattices
Michael J. Motala, Xiang Zhang, Pawan Kumar +23
Heterostructure materials form the basis of much of modern electronics, from transistors to lasers and light-emitting diodes. Recent years have seen a renewed focus on creating het…
Direct imaging of antiferromagnetic domains and anomalous layer-dependent mirror symmetry breaking in atomically thin MnPS
Zhuoliang Ni, Huiqin Zhang, David Hopper +8
We have developed a sensitive cryogenic second-harmonic generation microscopy to study a van der Waals antiferromagnet MnPS. We find that long-range Néel antiferromagnetic orde…
Exciton-Photonics: From Fundamental Science to Applications
Surendra B. Anantharaman, Kiyoung Jo, Deep Jariwala
Semiconductors in all dimensionalities ranging from 0D quantum dots and molecules to 3D bulk crystals support bound electron-hole pair quasiparticles termed as excitons. Over the p…
A CMOS Compatible Aluminum Scandium Nitride-based Ferroelectric Tunnel Junction Memristor
Xiwen Liu, Jeffrey Zheng, Dixiong Wang +4
We report a complementary metal oxide semiconductor (CMOS) technology compatible ferroelectric tunnel junction memristor grown directly on top of a Silicon substrate using a scandi…
Efficacy of Boron Nitride Encapsulation against Plasma-Processing in van der Waals Heterostructures
Pawan Kumar, Kelotchi S. Figueroa, Alexandre C. Foucher +4
Two-dimensional (2D) transition metal dichalcogenides (TMDCs) are the subject of intense investigation for applications in optics, electronics, catalysis, and energy storage. Their…
Direct Visualisation of Out-of-Equilibrium Structural Transformations in Atomically-Thin Chalcogenides
Pawan Kumar, James P. Horwath, Alexandre C. Foucher +5
Two-dimensional (2D) transition metal dichalcogenides (TMDCs) have been the subject of sustained research interest due to their extraordinary electronic and optical properties. The…
