10.3.2 Phase changes Phase changes in this context refer to a material switching between crystalline states, or from a crystalline to amorphous state (or vice versa). The bonding arrangement of a given composition of atoms varies substantially between amorphous and various crystalline forms, for exa...
The discovery and control of new phases of matter is a central endeavour in materials research. The emergence of atomically thin 2D materials, such as transition-metal dichalcogenides and monochalcogenides, has allowed the study of diffusive, displacive and quantum phase transitions in 2D. In this...

Moving towards the Sb2Te3end of the compositional pseudo-binary line, the switching speed is further improved, but the amorphous-phase stability is weakened, with aTxas low as 85 °C9. Ab initio materials screening studies have recently shown that alloying with a suitable element, such as Sc...

Good order parameter can reflect the symmetry changes perfectly duringphase transition. 好的序参量能很好地反映相变过程中对称性的变化. 互联网 Both the monomer and the polymer network will depressphase transitiontemperatures. 不同的液晶态可通过控制铁电液晶的温度来获得. ...
The global demand for data storage and processing has increased exponentially in recent decades. To respond to this demand, research efforts have been devoted to the development of non-volatile memory and neuro-inspired computing technologies. Chalcogeni
5b), which is based on a single-phase medium (ideal gas) and consisting of four quasi-static thermodynamic legs (two isothermal which contributes sensible heat, and two adiabatic legs, and all four legs require gradual pressure/volume changes). Here, instead, we propose to use latent heat ...
