Strain Engineering of Low-Dimensional Materials for Emerging Quantum Phenomena and Functionalities

Jin Myung Kim et al.

Summary: Recent discoveries of exotic physical phenomena in quantum materials have led to increased interest in studying the effects of strain on quantum states. By altering atomic spacing and crystal symmetry, strain engineering can effectively manipulate quantum phenomena and functionalities. This review focuses on recent advances in strain-tunable quantum effects in low-dimensional quantum materials.

Unveiling Electronic Behaviors in Heterochiral Charge-Density-Wave Twisted Stacking Materials with 1.25 nm Unit Dependence

Liwei Liu et al.

Summary: In this study, the heterochiral CDW stackings in bilayer NbSe2 with high spatial resolution were investigated. Well-defined heterochiral stackings were found, which showed significantly different electronic states compared to the homogeneous states in homochiral stackings. The different electronic behaviors were spatially localized within each SOD with a size of 1.25 nm, and the gap sizes were determined by the types of SOD stackings. Density functional theory calculations matched the experimental measurements well and revealed the SOD-stacking-dependent correlated electronic states and antiferromagnetic/ferromagnetic couplings. These findings provide a deep understanding of the spatial distribution of interlayer stacking and the modulation of spintronic states, which is helpful for CDW-based nanoelectronic devices.

Hard Ferromagnetism Down to the Thinnest Limit of Iron-Intercalated Tantalum Disulfide

Samra Husremovic et al.

Summary: This study demonstrates that Fe-intercalated TaS2 can maintain ferromagnetic order down to the thinnest limit and exhibit giant coercivity. By investigating the effects of dimensionality, degree of intercalation, and intercalant order/disorder on the magnetic behavior, we show that chemical intercalation can tailor the properties of low-dimensional magnetic materials.

Artificial heavy fermions in a van der Waals heterostructure

Viliam Vano et al.

Summary: The study demonstrates the synthesis and characterization of a two-dimensional van der Waals heterostructure hosting artificial heavy fermions, providing a tunable platform for investigations of heavy-fermion physics. Using scanning tunnelling microscopy and spectroscopy, the researchers show that depending on the stacking order of the monolayers, either localized magnetic moments and the associated Kondo effect, or conduction electrons with a heavy-fermion hybridization gap can be revealed. The experiments realize an ultimately tunable platform for future experiments probing enhanced many-body correlations, dimensional tuning of quantum criticality and unconventional superconductivity in two-dimensional artificial heavy-fermion systems.

Structural phase transition from 1H to 1T′ at low pressure in supported monolayer WS2 : Raman study

Anoop Thomas et al.

Summary: Pressure-dependent Raman studies on monolayer 1H tungsten disulfide supported on a polymer substrate up to 20 GPa reveal a phase transition to a mixed phase of 1T' and 1H above 8 GPa with the appearance of new Raman modes. The results indicate that biaxial compressive strain induces the phase transition at a relatively lower pressure in polymer-supported monolayer compared to bulk WS2.

Electrical Gating of the Charge-Density-Wave Phases in Two-Dimensional h-BN/1T-TaS2 Devices

Maedeh Taheri et al.

Summary: This study looks at the electrical gating of charge density-wave phases and current in h-BN-capped three-terminal 1TTaS2 heterostructure devices. It shows that a gate bias can influence the hysteresis associated with the transition between nearly commensurate and incommensurate charge-density-wave phases. The presence of abrupt spikes in current while sweeping the gate voltage suggests an electric-field effect rather than self-heating.
