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.

Gas Chromatography: Types of Detectors-II

Gas Chromatography: Types of Detectors-II

In gas chromatography, different detectors are employed to meet specific analytical needs. These detectors are often categorized based on their detection mechanisms and the types of compounds they are best suited to analyze. Thermal Conductivity Detectors (TCD), Flame Ionization Detectors (FID), and Electron Capture Detectors (ECD) represent common categories, each with unique operating principles and applications. However, beyond these, several other detectors are designed for more specialized...

Determination of Crystal Structures

Determination of Crystal Structures

In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...

Area of Science:

Optoelectronics
Semiconductor Devices
Photonics

Background:

Gallium arsenide (GaAs) electroabsorption avalanche photodiode (EAP) detectors are fabricated on n-n(+) GaAs waveguides.
Traditional GaAs photodetectors have limitations in detecting wavelengths beyond their normal absorption edge.

Purpose of the Study:

To investigate the performance of GaAs EAP detectors for detecting sub-bandgap radiation.
To explore the potential applications of these EAP detectors in optical communications.

Main Methods:

Fabrication of EAP detectors in n-n(+) GaAs waveguides.
Characterization of detector response to below band gap radiation from GaAs lasers and 1.06-mum Nd:YAG lasers.
Evaluation of analog signal detection capabilities and distortion levels.

Main Results:

EAP detectors demonstrated responsivity to wavelengths beyond the normal GaAs absorption edge, attributed to the Franz-Keldysh effect.
Measured absorption and responsivity indicate suitability for detecting below band gap radiation.
Analog signals were detected with less than 6% distortion.

Conclusions:

GaAs EAP detectors are effective for detecting sub-bandgap radiation due to the Franz-Keldysh effect.
These detectors offer potential applications in analog signal detection with low distortion.
The devices are suitable for time- and frequency-demultiplexing in optical systems.
