Biasing of P-N Junction

Biasing of P-N Junction

The operation of a p-n junction diode involves various biasing conditions, including forward bias, reverse bias, and equilibrium.
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...

Dielectric Polarization in a Capacitor

Dielectric Polarization in a Capacitor

The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general, dielectrics can be of two types: polar and nonpolar. In a polar dielectric, the positive and negative charges in the molecules are separated by a distance and hence have a permanent dipole moment. In contrast, no such charge separation exists in a nonpolar dielectric, however the nonpolar molecules get polarized in the presence of an external electric...

Potential Due to a Polarized Object

Potential Due to a Polarized Object

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Propagation of Action Potentials

Propagation of Action Potentials

The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

Biasing of Metal-Semiconductor Junctions

Biasing of Metal-Semiconductor Junctions

Biasing metal-semiconductor junctions involves applying a voltage across the junction. Specifically, the metal is connected to a voltage source, while the semiconductor is grounded. This technique is essential for controlling the direction and magnitude of current flow in electronic devices, including diodes, transistors, and photovoltaic cells.
In Schottky junctions, where the semiconductor is n-type, applying a positive voltage to the metal relative to the semiconductor reduces its Fermi...

Group Polarization

Group Polarization

Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Summary

Noise can trigger polarization switching in bistable systems with significant dynamical correlations. In contrast, high noise collapses bistability in large networks, but causes irreversible switching in sparse networks.

Area of Science:

Complex Systems Dynamics
Network Science
Statistical Physics

Background:

Bistability and noise are common in complex systems, influencing their function and resilience.
Understanding how noise affects system polarization is crucial for predicting behavior.

Purpose of the Study:

To investigate the role of noise in inducing polarization switching in bistable systems.
To explore the impact of network structure and dynamical correlations on noise-induced transitions.

Main Methods:

A simple three-state dynamical process was modeled.
Simulations were conducted on fully connected and sparsely connected networks, as well as multiplex networks.

Main Results:

Significant dynamical correlations enable noise to induce polarization switching.
In large, fully connected networks, noise leads to an unpolarized state.
Sparse networks exhibit abrupt, irreversible polarization switching with increased noise.
In multiplex networks, a dominant layer influences polarization switching.

Conclusions:

The interplay between noise and dynamical correlations can cause discontinuous transitions in bistable systems.
Mean-field descriptions are insufficient to explain these noise-induced phenomena.
