Research topics from publications: Tunable Electronics in Large-Area Atomic Layers of Boron–Nitrogen–Carbon; Perturbation-tuned triple spiral metamagnetism and tricritical point in kagome metal ErMn6Sn6. Representative work: We report on the low-temperature electrical transport properties of large area boron and nitrogen codoped graphene layers (BNC). The temperature dependence of resistivity (5 K < T < 400 K) of BNC layers show semiconducting nature and display a band gap which increases with B and N content, in sharp contrast to large area graphene layers, which shows metallic behavior. Our investigations show that the amount of B dominates the semiconducting nature of the BNC layers. This experimental observations agree with the density functional theory (DFT) calculations performed on BNC structures similar in composition to the experimentally measured samples. In addition, the temperature dependence of the Abstract Kagome materials are of topical interest for their diverse quantum properties linked with correlated magnetism and topology. Here, we report anomalous hydrostatic pressure ( p ) effect on ErMn 6 Sn 6 through isobaric and isothermal-isobaric magnetization measurements. Magnetic field ( H ) suppresses antiferromagnetic T N while simultaneously enhancing the ferrimagnetic T C by exhibiting dual metamagnetic transitions, arising from the triple-spiral-nature of Er and Mn spins. Counter-intuitively, pressure enhances both T C and T N with a growth rate of 74.4 K GPa −1 and 14.4 K GPa −1 respectively. Pressure unifies the dual metamagnetic transitions as illustrated through p-H phase diag
