An Integrated Automated Design for an Atomic Layer Photoluminescent Spectroscopy System

An automated atomic-layer photoluminescence (PL) spectroscopy system has been developed to minimize human intervention and reduce errors during the characterization of quantum-scale electronic materials. The platform unifies laser control, cryogenic sample positioning, data acquisition, and spectral post-processing within a single workflow. Manual procedures required for PL measurements, spectral analysis, and piezo-driven spatial mapping have been replaced by software-controlled routines. In Prof. Chitraleema Chakraborty’s laboratory at the University of Delaware, an interface was created between LightField™ (a software that controls Princeton Instruments cameras and spectrographs) and an ANC-300 piezo-positioner, enabling unattended multi-point PL experiments and automatic generation of piezoelectric heat maps. System parameters were fine-tuned to satisfy experimental constraints, yielding a reliable, high-throughput tool for probing the quantum properties of two-dimensional materials.
