Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
The ATR process begins by directing a beam...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

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.

Atomic Absorption Spectroscopy: Atomization Methods

Atomic Absorption Spectroscopy: Atomization Methods

Atomic Absorption Spectroscopy (AAS) atomizes samples through flame atomization or electrothermal atomization. Flame atomization typically involves a nebulizer and spray chamber assembly to combine the sample with a fuel–oxidant mixture, creating a fine aerosol mist that enters a burner. Typically, the fuel and oxidant are combined in an approximately stoichiometric ratio. However, for atoms that are easily oxidized, a fuel-rich mixture may be more advantageous. Only about 5% of the aerosol...

Infrared (IR) Spectroscopy: Overview

Infrared (IR) Spectroscopy: Overview

When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

Background:

Atomic Layer Deposition (ALD) is crucial for thin-film fabrication.
Real-time surface analysis during ALD is challenging.
Existing methods lack sufficient time resolution for dynamic studies.

Purpose of the Study:

To develop a sub-second time-resolution surface infrared spectroscopy method for ALD.
To investigate the dynamic processes occurring during an average ALD cycle.
To optimize experimental parameters for surface species analysis.

Main Methods:

Utilized a rapid-scan Fourier transform infrared (FT-IR) spectrometer for fast spectral acquisition.
Employed a buried metal layer (BML) substrate to enhance surface species absorption and enable surface-specific analysis.
Synchronized interferogram acquisition (120 ms) over multiple ALD cycles.
Performed simulations to understand reflectivity changes and BML enhancement decay.

Main Results:

Achieved sub-second time resolution for surface infrared spectra during ALD.
Successfully differentiated surface species from gas-phase or window-adsorbed species using BML substrates.
Identified origins of increased reflectivity due to phonon absorption in oxide layers.
Quantified the decay of BML enhancement as oxide layers grow.

Conclusions:

The developed method provides unprecedented temporal resolution for in-situ ALD surface studies.
BML substrates are effective for enhancing surface sensitivity and enabling surface-specific infrared spectroscopy.
Simulations aid in interpreting spectral data and optimizing experimental conditions for ALD process control.
