Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

The Quantum-Mechanical Model of an Atom

58.1K
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

Phase Transitions

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

Properties of Transition Metals02:58

Properties of Transition Metals

29.9K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

Area of Science:

  • Materials Science
  • Quantum Dot Technology
  • Infrared Spectroscopy

Background:

  • Colloidal quantum dots (CQDs) are explored for visible to short-wave infrared applications.
  • Achieving stable n-doping in CQDs is crucial for mid-infrared intraband transitions.

Purpose of the Study:

  • Investigate mid-infrared intraband transitions in InAs, InAs/InP, and InAs/ZnSe CQDs.
  • Explore the potential of CQDs for mid-infrared detection and emission.

Main Methods:

  • Utilized electrochemistry to study quantum dot films.
  • Analyzed state-resolved mobility, electron filling, and intraband absorption.
  • Characterized InAs, InAs/InP, and InAs/ZnSe CQDs with a 1.4 μm energy gap.

Main Results:

  • Observed state-resolved mobility, electron filling, and intraband absorption (3-8 μm) in CQD films.
  • Determined specific electrochemical potentials for n-doping InAs/ZnSe and InAs/InP.
  • Achieved stable n-doping of the 1Se state in InAs/InP CQDs, showing intraband absorption (3-5 μm) and luminescence (5 μm).
