Tailoring electronic properties and polarization relaxation behavior of MoS2 monolayers for electromagnetic energy dissipation and wireless pressure micro-sensor

A Flexible, Mechanically Strong, and Anti‐Corrosion Electromagnetic Wave Absorption Composite Film with Periodic Electroconductive Patterns

“…According to the effective medium and free electron theories (ε″ ≈ 1/2πε 0 ρf), the ε′ and ε″ values were determined by electron transmission and electrical conductivity. [19,[51][52][53][54] With the dissolution of copper, the complex permittivity of these composite films dropped in a cliff-like manner, and the real and imaginary parts of the ACP film finally stabilized at 23 ± 2 and 6 ± 1, respectively. For the EMW absorbing materials, high EM parameters not only brought strong attenuation, but also resulted in high reflectivity or poor impedance matching.…”

Covalent Bonding of MXene/Reduced Graphene Oxide Composites for Efficient Electromagnetic Wave Absorption

“…The extensive use of electromagnetic waves (EM), which offers many conveniences for people’s lives but also results in electromagnetic radiation pollution that harms both electronic devices and the human body, is inextricably linked to the development of electronic items and equipment. − As a result, an increasing number of researchers are focused on researching effective EMA materials in the 2–18 GHz frequency range. The perfect EM material frequently exhibits the properties of being light in weight, thin in thickness, having a wide absorption band, and performing well in absorption. − Due to their unique structures and dimensions, two-dimensional materials in recent years have demonstrated excellent EMA properties, including MXene, − graphene, − graphite, − carbon fibers, − and others.…”

Boosted interfacial charge dynamics on the SnO2/SnS2 heterointerface by gradient sulfur diffusion for microwave absorption and electric–thermal conversion

“…[24][25][26][27] For example, Xu et al designed high-performance vertically aligned MoS 2 monolayers on N-doped graphene absorbers with the guidance of DFT calculations. 28 Lv et al explains the changes of the SnO/SnO 2 heterojunction in interfacial polarization and electromagnetic wave absorption by calculating the work function. 29 In this work, DFT calculations were employed to evaluate the electronic properties, dipole moments, and polarization of SnO 2 , SnS 2 , and SnS 2 /SnO 2 heterostructures theoretically.…”
