Metastable state | Phase transition, Kinetic energy, Equilibrium
网页Metastable state, in physics and chemistry, particular excited state of an atom, nucleus, or other system that has a longer lifetime than the ordinary excited states and that generally has a shorter lifetime than the lowest, often stable, energy state, called the ground state.
Metastable Definition & Meaning - Merriam-Webster
网页The meaning of METASTABLE is having or characterized by only a slight margin of stability. How to use metastable in a sentence.
Metastable States – energy levels, forbidden transitions, upper …
网页Metastable states are excited states e.g. of atoms or ions which have a relatively long lifetime, resulting from only weak spontaneous emission.
网页Metastability is a common phenomenon in nature, with plenty of examples in physics, chemistry, and biology. Similar behavior may be also detected while studying certain phenomena in economics and social sciences.
Metastable - Vocab, Definition, and Must Know Facts - Fiveable
网页A metastable state is an excited state of an atom that has a longer lifetime than typical excited states. It delays returning to the ground state, often requiring external factors to prompt de-excitation.
Metastability: A Brief Introduction Through Three Examples
网页2019年11月17日 · Metastability is a very frequent phenomenon in nature. It also finds many applications in science and engineering. A noticeable basic feature is the presence of “quasi-equilibria states” and relatively sudden transitions between them.
2.6: Resonant Tunneling, and Metastable States
网页2022年1月29日 · This is just the standard differential equation, \[\frac{d W}{d t}=-\frac{1}{\tau} W,\] of the exponential decay, \(W(t)=W(0) \exp \{-t / \tau\}\), where the constant \(\tau\), in our case equal to \[\tau=\frac{m a^{2}}{\pi n \hbar} \alpha^{2},\] is called the metastable state’s lifetime. Using Eq.
Metastable state - Oxford Reference
网页A condition of a system in which it has a precarious stability that can easily be disturbed. It is unlike a state of stable equilibrium in that a minor disturbance will cause a system in a metastable state to fall to a lower energy level.
Metastable State - SpringerLink
网页A metastable state occurs in the bcd range, where the temperature is first low, then it rises suddenly. This metastable state is defined as the first-order metastable state. Accordingly, the existence time of the metastable state is t 1 + t 2.
Making the most of metastability | Science - AAAS
网页2022年8月18日 · Subsequent rapid quenching from high temperature preserves the desired metastable structure at ambient conditions. This presents a promising strategy to control the structure of a material by tuning the thermodynamic and kinetic conditions, preserving certain desirable metastable phases.
