Evidence of electronic states driving current-induced insulator-to-metal transition
V. K. Bhartiya, R. Hartmann, F. Forte +16
On demand current-driven insulator-to-metal transition (IMT) is pivotal for the next generation of energy-efficient and scalable microelectronics. IMT is a key phenomenon observed…
Dispersive dark excitons in van der Waals ferromagnet CrI3
W. He, J. Sears, F. Barantani +11
Spin-flip dark excitons are optical-dipole-forbidden quasiparticles with remarkable potential in optoelectronics, especially when they are realized within cleavable van der Waals m…
Magnetic excitations and absence of charge order in the van der Waals ferromagnet FeGeTe
V. K. Bhartiya, T. Kim, J. Li +12
Understanding the ground state of van der Waals (vdW) magnets is crucial for designing devices leveraging these platforms. Here, we investigate the magnetic excitations and charge…
Capping effects on spin and charge excitations in parent and superconducting Nd1-xSrxNiO2
S. Fan, H. LaBollita, Q. Gao +19
Superconductivity in infinite layer nickelates Nd1-xSrxNiO2 has so far been achieved only in thin films raising questions on the role of substrates and interfaces. Given the challe…
