The de Broglie Wavelength02:32

The de Broglie Wavelength

26.0K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

269
Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy  (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

Atomic Emission Spectroscopy: Overview

2.4K
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

Transmission Electron Microscopy

5.6K
In 1931, physicist Ernst Ruska—building on the idea that magnetic fields can direct an electron beam just as lenses can direct a beam of light in an optical microscope—developed the first prototype of the electron microscope. This development led to the development of the field of electron microscopy. In the transmission electron microscope (TEM), electrons are produced by a hot tungsten element and accelerated by a potential difference in an electron gun, which gives them up to 400...

Electron Microscope Tomography and Single-particle Reconstruction

2.4K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Overview of Microscopy Techniques

10.6K
The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Area of Science:

  • Quantum mechanics
  • Atomic physics
  • Ultrafast spectroscopy

Background:

  • Electronic wave packets exhibit both temporal and spatial evolution due to delocalized electronic states.
  • Spatial evolution of wave packets has been experimentally inaccessible on the attosecond timescale.
  • Understanding electron dynamics is crucial for fields like materials science and quantum computing.

Purpose of the Study:

  • To develop and apply a novel experimental technique to probe the spatial dynamics of electronic wave packets.
  • To investigate the attosecond-scale spatial evolution and dynamics of hole density in heavy atomic cations.
  • To capture the ultrafast charge dynamics and wave packet motion in krypton and xenon.

Main Methods:

  • Development of a phase-resolved two-electron-angular-streaking method.
  • Application of the technique to study krypton and xenon cations.
  • Attosecond time-resolved imaging of electronic wave packet spatial evolution.

Main Results:

  • The spatial evolution of an ultrafast spin-orbit wave packet in the krypton cation was imaged.
  • The motion of an even faster wave packet in the xenon cation was captured for the first time.
  • An electronic hole in xenon was observed to refill 1.2 femtoseconds after its creation, with filling occurring on the opposite side of its birth.

Conclusions:

  • The developed method provides unprecedented access to the spatial dynamics of electronic wave packets at the attosecond timescale.
  • Ultrafast charge dynamics, including hole refilling and spatial wave packet motion, can be precisely imaged in heavy atoms.
  • This work opens new avenues for exploring fundamental electron behavior in atoms and molecules.
