This master's thesis explores the effects of substrates and lithographic processes on 1T-TaS$_2$ samples, known for their complex phase diagram with multiple charge density wave phases and a hidden metastable state. We investigated how different fabrication methods influence sample properties, aiming to reduce unwanted effects arising from the fabrication process. Furthermore, we introduced alternative preparation methods for 1T-TaS$_2$ samples, ensuring that the material's transport properties are showcased without additional modifications due to the fabrication technique. With these improved methods, we analyzed how 1T-TaS$_2$ behaves when reducing sample thickness and whether the outcomes align with previous findings. Additionally, we examined how same factor aslo impact the hidden metastable state. A more stable metastable state could have substantial practical implications, potentially bringing 1T-TaS$_2$ closer to practical uses, such as in memristors.
