Abstract
Processing methods employing laser are often used to tailor semiconductors. For example, crystallization of semiconductors is induced via the interaction between laser and semiconductors – laser crystallization. While laser crystallization is widely used in preparing thin films made of a single chemical element, extending its use for those containing multiple chemical elements (e.g., metal oxides) could unfold applications currently not achievable. In this paper, a continuous-wave laser diode with a micrometer-scale chevron-shaped beam profile – micro chevron laser beam (μ-CLB) – is exploited to crystallize non-single-crystal CuO thin films deposited on fused silica substrates. Resulting single-crystal Cu2O strips are studied to reveal their unique characteristics associated with key parameters of the crystallization process.
