What is the difference between stable and metastable?
The distinction between stable and metastable equilibrium is generally that the stable equilibrium state is “truly unchanging”, or unchanging given in- definite time, whereas the metastable state may be changing, but too slowly to be observed (see Quota- tions).
What is metastable equilibrium with example?
Thus, the state of relatively stable or metastable equilibrium is defined as the state in which a system remains for a long period of time, and any slight disturbance causing the system to deviate from the metastable state does not result in the system passing into another state.
What is metastable state in phase diagram?
metastable state in phase diagram. metastable state in phase diagram. The method of molecular dynamics is used to treat the metastable states of Lennard-Jones crystal and liquid at different temperatures and pressures, including the negative-pressure region.
What causes metastable state?
Metastability can occur when signals are transferred between circuitry in unrelated or asynchronous clock domains. The mean time between metastability failures is related to the device process technology, design specifications, and timing slack in the synchronization logic.
What causes metastability in flip-flop?
Metastability in digital systems occurs when two asynchronous signals combine in such a way that their resulting output goes to an indeterminate state. A common example is the case of data violating the setup and hold specifications of a latch or a flip-flop.
Why are metastable materials important to thermodynamics?
“Although we still don’t fully understand which materials can be made and how, mapping the underlying thermodynamics is an important first step.” Metastable materials, or materials that transform to another state over a long period of time, are ubiquitous in both nature and technology and often have superior properties.
Can a diamond be a metastable form of carbon?
They say diamonds are forever, but diamonds in fact are a metastable form of carbon that will slowly but eventually transform into graphite, another form of carbon.
Which is the best measure of metastability of a flip flop?
Metastability is typically described by four measurements of flip-flop performance — MTBF, T, To and tr. MTBF is the “mean-time-between-failure” of a flip-flop. where tr is metastability resolution time, maximum time the output can remain metastable without causing synchronizer failure.
