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.

Background:

Solar-blind ultraviolet (UV) detection is crucial for various applications, including flame detection and missile warning systems.
Existing UV detectors often require external filters to block visible light, adding complexity and reducing efficiency.
High-aluminum-content AlGaN-based materials are promising for solar-blind applications due to their wide bandgap.

Purpose of the Study:

To synthesize, fabricate, and test a 320x256 focal plane array (FPA) of solar-blind AlGaN-based detectors.
To achieve high external quantum efficiency (EQE) and demonstrate reliable solar-blind operation.
To integrate the FPA with a readout integrated circuit (ROIC) and evaluate its imaging performance.

Main Methods:

Utilized pulse atomic layer deposition for metalorganic chemical vapor deposition (MOCVD) growth of high-quality, crack-free AlGaN layers with high aluminum composition.
Hybridized the AlGaN FPA to a matching ISC 9809 ROIC for operation in a SE-IR camera system.
Developed an opaque masking technology to mitigate the visible light response of the ROIC, eliminating the need for external filtering.

Main Results:

Demonstrated solar-blind operation across the entire array, with peak detection at wavelengths ≤ 256 nm and a three-order-of-magnitude drop-off by ~285 nm.
Achieved an average peak responsivity of 75 mA/W at 254 nm, corresponding to an external quantum efficiency (EQE) of ~37%.
Investigated the uniformity and imaging properties of the fabricated FPA, confirming its suitability for practical applications.

Conclusions:

Successfully fabricated a high-performance 320x256 AlGaN-based solar-blind FPA in-house.
The developed opaque masking technology effectively enables solar- and visible-blind operation, simplifying system design.
The FPA exhibits promising characteristics for advanced UV imaging applications requiring high sensitivity and uniformity.
