In this article, we investigate the development and use of thermal memory elements based on thin-film aluminum devices silicon wafer. To stabilize their operation reduce number errors during read/write process information in such devices, propose an algorithm (referred to as floating zero algorithm) for adjusting temperature conditions cells. This controls cells under varying ambient conditions. We tested performance using experimental sample at room temperature. Additionally, conducted a study degradation high electrothermal loading The results showed that starts when single current pulse duration τi ≥ 100 µs amplitude density ji 8.5 × 1010 A/m2) flows through device. criterion determining safe area γ device investigation experimentally determine its value = 6.0(VA√s).

While electromagnetic metamaterials completely revolutionized optics and radio frequency engineering, recent progress in the development of conceptually related electronic was more slow. Similar to metamaterials, which engineer material response field a photon, purpose is affect electron propagation its wave function by changing electric field. This makes an ideal tool for engineering light–matter interaction semiconductors superconductors. Here, we propose use Fermi’s quantum refraction, previously observed terahertz spectroscopy Rydberg atoms two-dimensional surface states, as novel metamaterial design. In particular, demonstrate several potential applications this concept superconductors “universal dots” designed operation range.

Abstract A novel photonic device composed of graphene and black phosphorus (G-BP) has been proposed, which achieves high-performance plasmon-induced transparency (PIT) effect within the THz range maintains substantial tunability anisotropy. The anisotropy PIT arises from near-field coupling between two bright modes characterized by distinct effective electron masses BP, resulting window at 33.35 for TE polarization 26.92 TM polarization. Through modulation Fermi energy in graphene, doping levels BP geometric parameters separately, a tunable is achieved. Notably, convergence or divergence anisotropic windows can be well manipulated with different levels. Furthermore, proposed G-BP exhibits high sensitivity to changes surrounding refractive index substrates, maximum 12.04 THz/RI, rendering it suitable sensor applications. Overall, notable effects performance, tunability, great sensitivity, stability, making promising candidate applications sensors, polarizers, switchers.
