BIBO stability of continuous and discrete -time systems01:24

BIBO stability of continuous and discrete -time systems

395
System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....

Metal-Semiconductor Junctions

350
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...

Fermi Level

598
The Fermi-Dirac function is represented by an S-shaped curve indicating the probability of an energy state being occupied by an electron at a given temperature. The Fermi level is the energy level at which there is a fifty percent chance of finding an electron, and it is positioned between the lower-energy valence band and the higher-energy conduction band.
At absolute zero temperature, electrons fill all energy states up to the Fermi level, leaving upper states empty. As the temperature rises,...

Physiological Barriers

3.5K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

Fermi Level Dynamics

246
The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.
The work...

Schottky Barrier Diode01:27

Schottky Barrier Diode

349
Schottky barrier diodes are specialized semiconductor devices characterized by their unique construction. This construction involves combining a metal layer with a moderately doped n-type semiconductor material. This combination leads to the formation of a Schottky barrier, a pivotal element that defines the diode's operational characteristics. The core functionality of Schottky barrier diodes is their capacity to allow current to flow in only one direction due to their distinctive...

Summary
This summary is machine-generated.

We discovered that boundary modes in finite lattices can be trapped, defying conventional exponential decay. This phenomenon, similar to bound states in the continuum, allows for complete localization within minimal lattice sites.

Area of Science:

  • Condensed Matter Physics
  • Photonics
  • Wave Phenomena

Background:

  • Boundary modes in finite lattices typically exhibit tunneling to the opposite side, leading to unwanted couplings.
  • Tunneling probability is conventionally understood to decay exponentially with system size, necessitating large lattices for negligible coupling.

Purpose of the Study:

  • To investigate the possibility of trapping boundary modes within a finite number of lattice sites.
  • To explore mechanisms that allow boundary modes to be completely localized, irrespective of conventional tunneling behavior.

Main Methods:

  • Theoretical analysis of boundary mode behavior in finite lattices.
  • Experimental validation using dielectric photonic crystals at microwave frequencies.
  • Investigation of specific wavevectors where tunneling probability vanishes.

Main Results:

  • Demonstrated that tunneling probability for certain boundary modes can vanish at specific wavevectors.
  • Observed complete trapping of boundary modes within very few lattice sites, even without a well-defined bulk bandgap.
  • Found that the number of trapped states corresponds to the number of lattice sites normal to the boundary.

Conclusions:

  • Introduced a novel phenomenon of finite barrier-bound states, analogous to bound states in the continuum.
  • Provided experimental evidence for this peculiar trapping mechanism in photonic crystals.
  • Highlighted the potential for flexible control over light coupling and manipulation.
