Semiconductors

1.6K
There is variation in the electrical conductivity of materials - metals, semiconductors, and insulators that are showcased with the help of the energy band diagrams.
Metals such as copper (Cu), zinc (Zn), or lead (Pb) have low resistivity and feature conduction bands that are either not fully occupied or overlap with the valence band, making a bandgap non-existent. This allows electrons in the highest energy levels of the valence band to easily transition to the conduction band upon gaining...

Types of Semiconductors

1.5K
Intrinsic semiconductors are highly pure materials with no impurities. At absolute zero, these semiconductors behave as perfect insulators because all the valence electrons are bound, and the conduction band is empty, disallowing electrical conduction. The Fermi level is a concept used to describe the probability of occupancy of energy levels by electrons at thermal equilibrium. In intrinsic semiconductors, the Fermi level is positioned at the midpoint of the energy gap at absolute zero. When...

Metal-Semiconductor Junctions

1.1K
The contact of metal and semiconductor can lead to the formation of a junction with either Schottky or Ohmic behavior.
Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...

Biasing of Metal-Semiconductor Junctions01:27

Biasing of Metal-Semiconductor Junctions

673
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...

Predator-Prey Interactions02:39

Predator-Prey Interactions

21.8K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Van der Waals Interactions01:24

Van der Waals Interactions

72.2K
Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

Area of Science:

  • Nonlinear dynamics
  • Laser physics
  • Complex systems

Background:

  • Chimera states, patterns of coexisting coherence and incoherence, have been observed in smaller coupled oscillator networks.
  • Previous studies on chimera states in lasers primarily used global or nearest-neighbor coupling schemes.
  • Large arrays of coupled lasers offer technological advantages but require investigation into their collective dynamics.

Purpose of the Study:

  • To numerically investigate the collective dynamics of a large array (200 elements) of nonlocally coupled semiconductor lasers.
  • To explore the formation and characteristics of chimera states in such systems.
  • To identify key parameters influencing the emergence and robustness of chimera states.

Main Methods:

  • Numerical simulations of a large array of 200 nonlocally coupled semiconductor lasers.
  • Analysis of spatiotemporal patterns focusing on chimera states.
  • Systematic variation of crucial parameters: coupling strength, coupling phase, and nonlocal interaction range.

Main Results:

  • Demonstration of robust, multiclustered chimera states in a large array of nonlocally coupled semiconductor lasers.
  • Identification of a wide parameter space supporting these complex spatiotemporal patterns.
  • Quantitative characterization of the emergent (in)coherent domains within the laser array.

Conclusions:

  • Nonlocal coupling enables robust, multi-domain chimera states in large semiconductor laser arrays.
  • The findings suggest that chimera states are achievable in systems with technological relevance.
  • Proposed experimental setups provide a pathway for laboratory verification of these numerical results.
