Sentences with word «bistability»

In an attempt to mitigate these problems, scientists have considered the development of an optical digital computer, and one team has gone so far as to demonstrate the optical and electrical bistability for switching in a single transistor.

Compared to prior investigations, which contained optical hysteresis in cavities containing nonlinear absorptive and dispersive gain media, the operation principles as physical processes and operating mechanisms in transistor laser electro - optical bistabilities are considerably different.

Microparticle - based displays possess intrinsic bistability, exhibit extremely low power d.c. field addressing and have demonstrated high contrast and reflectivity.

It is the researchers» belief the operations of the electro - optical hysteresis and bistability in the compact form of the transistor laser can be utilized for high speed optical logic gate and flip - flop applications.

«Because of the switching path differences between coherent and incoherent cavity photon densities reacting with collector voltage modulation via Feng - Holonyak intra-cavity photon - assisted tunneling resulting in the collector voltage difference in switch - UP and switch - DOWN operations, the transistor laser bistability is realizable, controllable and usable,» Feng said.

E-paper's bistability also brings the added bonus of an electronic paper display consuming power only when the content on it is changing.

In physics, bistability means a system which exists in two stable equilibrium states, when all particles in a system are at rest and the total force on each particle is permanently zero.

Since the ultrathin metasurfaces are flexible and the polymer is soft, the whole system can be bent.Desired future improvements for this technology include bistability, cheaper materials and implementation with TFT arrays.

A large fraction of precipitation in the Amazon basin is recycled, and, therefore, simulations of Amazon deforestation typically generate ≈ 20 — 30 % reductions in precipitation (78), lengthening of the dry season, and increases in summer temperatures (79) that would make it difficult for the forest to reestablish, and suggest the system may exhibit bistability.
