有機半導體相比矽基半導體具有許多優勢，如低溫製造、柔性和低成本等。然而，開發高性能n型有機半導體對實現n型有機場效電晶體（OFETs）至關重要。

在本篇論文中，我們研究了在Au(111)表面上的C$_{12}$-PDI，該分子在苉(Picene)核長軸方向上引入了酰亞胺基(Imide)。目的是探索烷基鏈的性質及其作為保護基的潛力。所有掃描穿隧顯微鏡（STM）和掃描穿隧能譜（STS）測量均在77K和超高真空中的Au(111)基板上進行。
透過不同的製備和加熱，我們觀察了烷基鏈脫離過程的溫度依賴性。
我們成功實現了對烷基鏈的熱控制。這項研究展示了透過表面合成實現高性能n型有機半導體的可能性。
此外，我們也開發了一個基於Arduino的監測系統。該系統利用人耳作為固有的傅立葉變換（FFT）分析器，為監測隧道電流提供了更可靠的方法。 並且對STM的電流導線進行了更加牢固的維修，使他不會在時間的作用下再次損壞。

Organic semiconductors offer advantages over silicon-based semiconductors, such as low-temperature manufacturing, flexibility, and lower cost. However, developing high-performance n-type organic semiconductors is crucial to realizing n-type OFETs.

In my MSc research, we studied the adsorption of C$_{12}$-PDI, incorporating imides along the long-axis direction of the picene core. To explore the properties of alkyl and their potential as the protecting group. All the scanning tunneling microscope (STM) and scanning tunneling spectroscopy (STS) measurements are done on an Au(111) surface at 77K and in ultra-high vacuum.
With different preparations and heatings, we observed the temperature dependence of the alkyl chain detachment process.
We successfully achieved the thermal control of the alkyl chains.

Additionally, we present an Arduino-based monitoring process. Using the human ears as the inherent Fast Fourier Transform(FFT) machine which provides a more reliable way to spy the tunneling current.
We also carried out more robust repairs on the STM current cable to prevent them from breaking again over time.
