In graphite crystals, layers of graphene reside in three equivalent, but distinct, stacking positions typically referred to as A, B, and C projections. The order which the are stacked defines electronic structure crystal, providing an exciting degree freedom can be exploited for designing graphitic materials with unusual properties including predicted high-temperature superconductivity ferromagnetism. However, lack control sequence limits most research stable ABA form graphite. Here we...
The excellent electronic and mechanical properties of graphene allow it to sustain very large currents, enabling its incandescence through Joule heating in suspended devices. Although interesting scientifically promising technologically, this process is unattainable ambient environment, because quickly oxidises at high temperatures. Here, we take the performance graphene-based incandescent devices next level by encapsulating with hexagonal boron nitride (hBN). Remarkably, found that hBN...
Despite a rich choice of two-dimensional materials, which exists these days, heterostructures, both vertical (van der Waals) and in-plane, offer an unprecedented control over the properties functionalities resulted structures. Thus, planar heterostructures allow p-n junctions between different semiconductors graphene nanoribbons with well-defined edges; in observation superconductivity purely carbon-based systems realisation tunnelling transistors. Here we demonstrate simultaneous use...
Resistance drift of the amorphous states multilevel phase change memory (PCM) cells is currently a great challenge for commercial implementation reliable multiple-bit-per-cell technology. This paper reports observation stable intermediate state PCM cell that achieved through nonuniform heating with square current injection top electrode. Drift coefficient an order magnitude lower than reset and has weaker temperature dependence. Using finite-element simulations analytical model subthreshold...
{\alpha}-RuCl$_3$, a narrow-band Mott insulator with large work function, offers intriguing potential as quantum material or charge acceptor for electrical contacts in van der Waals devices. In this work, we perform systematic study of the optical reflection contrast {\alpha}-RuCl$_3$ nanoflakes on oxidized silicon wafers and estimate accuracy imaging technique to assess crystal thickness. Via spectroscopic micro-ellipsometry measurements, characterize wavelength-dependent complex refractive...
