SUNY Poly Associate Professor of Nanoengineering Dr. Spyros Galis and first author, recent SUNY Poly alum Dr. Mounika Kotha, recently published a paper in the Advanced Photonics Research journal, titled “Wavelength-Dependent Anisotropic Optical Properties in Layered GaTe for Polarization-Sensitive Applications.”

The research notes, “Anisotropic layered GaTe has emerged as a potential material for polarization-sensitive applications. However, there is ambiguity in identifying the b-axis in GaTe in existing reports. Proper identification is vital toward the fabrication of polarization-sensitive photodetectors and light sources. Herein, this ambiguity is addressed and a systematic structural and polarization-resolved optical study to identify the b-axis in GaTe is reported for a multitude of different sample thicknesses and laser excitation wavelengths. Furthermore, a broadband visible excitation window is identified for which GaTe exhibits photoluminescence anisotropy. These results highlight the potential of layered GaTe in polarization- and wavelength-sensitive applications.”
