Ferroelectrics Coupled with Unidirectional Rotation in Liquid Crystals

Jianyun Wu et al.

Summary: Studied the collective motion of chiral molecules and found that the unidirectional rotation of one-dimensional chiral hydrogen-bonding columns can lead to ferroelectricity. Especially in R-3BC, the unidirectional rotation reduces the energy of polarization inversion and effectively suppresses energy dispersion.

Simple molecular ferroelectrics: N,N′-dialkyl-terephthalamide derivatives in the solid phase

Moeko Kawana et al.

Summary: The simple molecules of N,N'-dialkyl-1,4-benzenedicarboxamide (CnIPA) can form a one-dimensional hydrogen-bonding molecular assembly, which undergoes a solid-solid phase transition through partial melting of alkyl chains. The phase transition behavior, dielectric constant, and ferroelectricity of CnIPA are affected by the alkyl chain length.

Designing Conductive-Bridge Phase-Change Memory to Enable Ultralow Programming Power

Zhe Yang et al.

Summary: The researchers propose a solution to the high power consumption problem in phase-change material (PCM) devices by designing and utilizing a new PCM alloy. By decomposing the alloy into a network of nanoscale crystalline domains and amorphous regions, the researchers are able to create conductive paths through nano-bridges formed in the interface region of the crystalline domains. This new PCM fabrication technology is compatible with current 3D integration technology and does not add any extra expenses or processing difficulties.

Insights into Chemically Fueled Supramolecular Polymers

Anastasiia Sharko et al.

Summary: Supramolecular polymerization can be controlled in space and time by chemical fuels. The activation and deactivation of a nonassembled monomer leads to self-assembly into a polymer and subsequent disassembly. This approach, which has been mastered by biology, has recently been achieved in fully artificial systems. Mathematical models have been developed to describe the activation, deactivation, assembly, and disassembly kinetics in different regimes of chemically fueled cooperative supramolecular polymerization, with the possibility of sustained oscillations. These models encourage further quantification in future studies.

Chemical design of organic ferroelectrics using dynamics of alkylamide chains

Takashi Takeda et al.

Summary: Polypeptide chains and alkylamide chains are important structural units used in the formation of protein secondary structures and characteristic molecular assemblies like liquid crystals and supramolecular polymers. The combination of alkylamide chains and functional Tc-electron frameworks enable multifunctional molecular materials with properties such as ferroelectricity, luminescence, high thermal stability, photoresponse, and current switching. Chiral alkylamide chains are effective in controlling dipole inversion and low coercive electric fields for memory devices, while influencing the physical properties of organic ferroelectrics in molecular assemblies.

Three Resistance States Achieved by Nanocrystalline Decomposition in Ge-Ga-Sb Compound for Multilevel Phase Change Memory

Liwei Zhang et al.

Summary: This paper explores the multilevel cell (MLC) capability in the phase change material Ge-Ga-Sb (GGS), achieving three resistance levels through SET operation and stabilizing them within a large operating voltage range. Compositional phase separation in nanocrystalline GGS enables the additional resistance level beyond 0 and 1, as revealed by atom probe tomography and electronic microscopy. The device also demonstrates small resistance drift in amorphous state and high thermal stability, making it suitable for practical applications in extreme conditions.
