These TNPs and TNTs have been used, among many applications, primarily in photocatalysis, third-generation photovoltaics, and sensors. In this work, we present a novel method for inducing crystallinity and transparency in vertically aligned amorphous (black and opaque) TNPs as an alternative to energy-intensive and time-consuming thermal annealing. Amorphous TNPs were prepared by anodising magnetron-sputtered Ti thin films deposited on FTO glass. To induce crystallinity, different intense pulsed white light (IPWL) flash protocols (varying voltage, current, and number of light pulses) were implemented and compared with a standard annealing protocol. Using magnetron sputtering as the starting point for TNP preparation allows the use of different substrates: rigid conductive glass or flexible polymer substrates. Here, we focus on FTO glass substrates and show that IPWL can crystallise anodic TNP layers at a reduced thermal budget, which is a prerequisite for future extension of this technology to flexible substrates.

While the average nearest-neighbor spacing between hillocks differed significantly, measuring 63.9 μm for the Al-2at.%Ta film and 2.5 μm for the Al-2at.%Cu film, the (m, σ)-diagram revealed that the geometry of hillocks was fundamentally similar and highly randomized. The grain sizes, measuring approximately 0.1 μm, were smaller than the average spacing between hillocks by one to three orders of magnitude. From a microstructural perspective, the observed hillock density was significantly lower than the frequency of potential hillock formation sites. The contribution of hillock formation to macroscopic stress relief accounted for approximately two-thirds of the total relaxed stress at 573 K in both alloy films. In addition, the area influenced by individual hillocks extended across the range represented by the spacing between hillocks. The spatial distributions with low hillock density in the AlTa films were attributed to higher thermal stresses at the onset of hillock formation.
