Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview

In inductively coupled plasma–mass spectrometry (ICP–MS), an inductively coupled plasma (ICP) torch is used as an atomizer and ionizer. Solid samples are dissolved and volatilized before being introduced into the high-temperature argon plasma, while solution samples are nebulized and passed through the high-temperature argon plasma. Plasma dissociates the analytes and ionizes their component atoms to form a mixture of positive ions and molecular species. The positive ions are then passed on to...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Principle

Inductively coupled plasma (ICP) is the most widely used plasma source in atomic emission spectroscopy (AES), also known as Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). The ICP source, or torch, consists of three concentric quartz tubes with argon gas flowing through them. A spark from a Tesla coil initiates the ionization of argon, generating a high-temperature plasma.
The ions and electrons produced interact with the fluctuating magnetic field created by a water-cooled...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

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.
Metal-Semiconductor Junctions01:24

Metal-Semiconductor Junctions

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 semiconductor's...

Summary

Gallium and Indium exhibit unique crystal structures. High pressure induces a close-packed structure in Gallium, and first-principles calculations predict this transition for Indium at extreme pressures.

Area of Science:

  • Condensed matter physics
  • Materials science
  • Computational physics

Background:

  • Gallium (Ga) and Indium (In) are Group-III elements known for unusual open ground-state crystal structures.
  • Experimental data shows Ga transforms to a close-packed structure under high pressure, but In has not exhibited this behavior.

Purpose of the Study:

  • To explain the difference in high-pressure structural behavior between Ga and In.
  • To predict the high-pressure phase transitions of In.
  • To identify the underlying mechanism governing structure determination in Group-III elements.

Main Methods:

  • First-principles calculations were employed to investigate the structural properties of Ga and In under pressure.
  • Analysis focused on the electronic structure, specifically the degree of s-p mixing of valence orbitals.

Main Results:

  • The study provides a simple explanation for the differing high-pressure behaviors of Ga and In.
  • A previously undiscovered transition of In to a close-packed structure at extreme pressures is predicted.
  • The degree of s-p mixing in valence orbitals is identified as the key mechanism determining the crystal structure.

Conclusions:

  • Group-III elements significantly deviate from the standard corresponding-state rule.
  • The electronic structure, particularly s-p orbital mixing, is crucial for understanding pressure-induced phase transitions in these elements.
  • Further experimental investigation into the high-pressure behavior of In is warranted.
