GHz-Bandwidth InAs Barrier Infrared Detector Performance Data for 3.0–3.7 μm

Grzegorz Gomółka published a dataset on figshare in May 2026 containing performance data for a mid-wave infrared photodetector. The data, stored in a 1.8 MB MAT file, supports research on high-speed photodetectors for the 3.0–3.7 μm spectral region. It documents the response speed and signal-to-noise performance of an InAs/InAsSbP nBp barrier detector operating at room temperature.

Use Cases

• Benchmarking detector bandwidth based on the reported -3 dB and –20 dB electrical bandwidth figures.
• Modeling high-frequency photodetection performance based on the signal-to-noise data exceeding 19 GHz.
• Comparing device architectures based on the description of a simple InAs-based structure without cascades or superlattices.

Strengths

• Performance metrics include specific bandwidth figures (2.3 GHz and 8.0 GHz) and a device diameter (121 μm).
• The dataset is associated with a published scientific result described as the best in its class for mid-infrared photodetectors.
• Data is shared under a permissive CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is small (1.8 MB), which may limit the scope of analysis.
