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...

Background:

Metal-oxide semiconductor field-effect transistor (MOSFET) based X-ray detectors offer high accuracy but suffer from permanent degradation under X-ray exposure, limiting their operational lifetime.
This degradation necessitates frequent replacement and impacts the long-term viability of X-ray imaging systems.

Purpose of the Study:

To investigate the potential of carbon nanotube (CNT) field-effect transistors (FETs) as a durable alternative for X-ray detection.
To evaluate the performance and stability of CNTFETs under X-ray irradiation compared to conventional MOSFET detectors.

Main Methods:

Carbon nanotubes were deposited onto SiO2 coated p-type silicon substrates using dielectrophoresis.
Fabricated CNTFET devices were characterized for their response to X-ray exposure, measuring gate voltage shift and source-drain current sensitivity.
Performance metrics were compared against established MOSFET-based X-ray detector technologies.

Main Results:

The developed CNTFET devices exhibited a significant gate voltage shift of 244 V Gy⁻¹.
A high source-drain current sensitivity of 382 nA Gy⁻¹ was achieved for the CNTFETs.
These performance metrics surpassed those reported for current MOSFET-based X-ray detector devices.

Conclusions:

Carbon nanotube field-effect transistors present a promising solution for X-ray detection, overcoming the limitations of permanent degradation associated with MOSFETs.
The demonstrated high sensitivity and voltage shift indicate the potential for enhanced performance and longevity in future X-ray imaging systems.
CNTFETs offer a pathway towards more robust and sustainable X-ray detector technology.
