The resulting acoustic signal can be detected using a variety of techniques: deflection-based photothermal (PT) methods [10; 11], ultrasonic detectors [12; 13], or gas-microphone configurations, either in reflection or in transmission using a minimum volume cell [14]. The generation of acoustic waves is a consequence of the PT effect, wherein absorbed electromagnetic energy from the excitation beam is converted into heat. In addition to generating acoustic waves, the PT effect also produces other detectable phenomena that do not rely on acoustic sensors [10; 11; 15; 16; 17]. For example, it may cause changes in the infrared spectrum of the sample, which can be captured via radiometry; induce gradients in the optical refractive index within the sample (utilized in thermal lens spectroscopy methods) or in the surrounding medium (mirage techniques); or be directly observed as surface temperature changes using calorimetric methods. This study focuses on the gas-microphone technique implemented using a minimum volume cell. This configuration has been developed in parallel with the more widespread reflection-mode PA techniques [14], and it has proven especially effective for the characterization of metals, semiconductors, and semiconductor devices [1]. In recent years, special attention has been given to developing time-domain PA techniques for real-time electronic characterization of semiconductor structures. However, a critical challenge in this domain is the deconvolution of signal contributions arising from charge carrier dynamics and those due to the detection system. This challenge motivates our current study. Previous studies have shown that frequency-domain PA spectroscopy [18] can be used to measure the electronic properties of semiconductors. However, these methods are generally not suitable for real-time measurements, which are increasingly important for industrial and biomedical applications [19]. In contrast, time-domain PA methods [20; 21; 22; 23] offer the potential for real-time characterization, but they require more advanced models and signal-processing techniques [22]. There are three main approaches to modeling PT and PA effects in semiconductors. The first approach assumes that photogenerated carriers influence the thermal conductivity, diffusivity, or relaxation times of the semiconductor, thereby affecting the temperature distribution and, ultimately, the generated pressure wave [24; 25; 26; 27]. The second approach utilizes the two-temperature model, treating electrons and lattice as separate thermal systems; this is particularly suited for highly doped or degenerate semiconductors [28; 29; 30; 31].
