## 1 Introduction  
Understanding the intricate morphological characteristics of organic semiconductors is crucial for enhancing their performance in organic electronic applications. Several solution-processable organic semiconductors such as 2,7-dioctyl[1]benzoth[3,2-b][1]benzothiophene (Cs-BTBT) [1, 2, 3], diketopyrrolopyrrole (DPP) based compounds [4, 5, 6],2,8-difluoro-5,11-bis(triethylsilylethylynyl)anthradithiophene (diF-TES ADT) [7; 8; 9], and 6,13-bis(trisisopropylsilylethylynyl)pentacene (TIPS pentacene) [10; 11; 12] have been extensively researched as benchmark examples and hold promise for use in organic thin film transistors (OTFTs) [13; 14; 15; 16], organic photovoltaics (OPVs) [17; 18; 19; 20; 21; 22; 23], as well as organic light-emitting diodes (OLEDs) [24; 25; 26; 27], due to the exceptionally high mobility and stability. Nevertheless, morphological issues including dendritic crystals [28; 29; 30], thermal cracks [31; 32], and grain boundaries [33; 34; 35] significantly influence the electrical properties and overall device reliability. Addressing these morphological challenges through optimized deposition conditions [36; 37] and post-treatment processes [38; 39], therefore, is essential for achieving consistent and reliable performance in organic electronic devices. By fine-tuning the fabrication process, it is possible to mitigate defects and enhance the structural integrity of the films, leading to improved device efficiency and longevity. This advancement can pave the way for the widespread adoption of organic semiconductors in flexible and wearable electronics and next-generation display technologies. _Dendritic crystals_: by using TIPS pentacene as an example, dendritic crystals tend to form with misorientation and poor substrate coverage when it is drop cast in toluene, leading to anisotropic charge transport [40]. Polarized optical micrographs of pristine TIPS pentacene films in Figure 1a,b display dendritic crystals exhibiting misorientation, as indicated by the red arrows. When TIPS pentacene was drop cast in an organic solvent toluene, it formed randomly-oriented crystals. Charge transport through these misoriented crystal needles is primarily anisotropic, as indicated by the various directions of the long axis (210) or charge transport paths. Additionally, the TIPS pentacene film displayed very low coverage on the substrate [41], marked by the triangles. This incomplete coverage can create regions with insufficient active material, further compromising the film's electrical properties. The measured hole mobility for such thin film morphology has been reported to show substantial variation, resulting in inconsistent performance of TIPS pentacene-based OTFTs [42; 43]. Figure 1: Polarized optical micrographs of pristine TIPS pentacene films displaying (**a,b**) dendritic crystals with misorientation, and (**c,d**) thermal cracks. Image (**b**) shares the same scale bar of 50 \(\upmu\)m as in (**a**), while image (**d**) shares the same scale bar of 100 \(\upmu\)m in (**c**).

Thermal cracks: resulting from stress during film formation or post-deposition annealing, these cracks may compromise structural integrity and disrupt charge transport pathways, posing a risk of device failure [46]. Figure 1c,d highlight the presence of thermal cracks, marked by the yellow arrows. These cracks are likely a result of thermal stress during the film formation or post-deposition annealing processes [47]. These cracks introduce discontinuities in the film, which can severely disrupt charge transport pathways and reduce overall device performance. [PERSON] et al. reported that these fissures form due to stress along specific crystallographic planes during heating, leading to disruptions in the TIPS pentacene's crystalline structure [48]. As a result, there is a noticeable decline in charge carrier mobility, with values dropping from 0.4-1.0 cm\({}^{2}\)/Vs to approximately 0.2 cm\({}^{2}\)/Vs post-cracking.
