| dc.description.abstract | 本論文主要研究碲(Te)材料中的磁性傳輸。碲的晶體透過化學氣相傳輸法(chemical vapor transport method)製造。在磁性傳輸方面，我們觀察到在施加平行於樣品電流的磁場時，樣品具有負磁阻的現象，此現象可以透過手徵性異常(chiral anomaly)來描述。施加垂直樣品電流磁場時產生的電阻震盪可以透過拓樸材料中的離散尺度不變性(discrete scale invariance in topological materials)來解釋。根據我們的實驗結果可以得知碲具有外爾材料(Weyl materials)的特性，並且能用於研究與外爾材料相關的物理現象。 | zh_TW |
| dc.description.abstract | This study reports the magnetotransport in tellurium (Te). The crystals of Te are synthesized using a chemical vapor transport method. In the magnetotransport characteristics, we observed that the sample had negative magnetoresistance when we applied a magnetic field parallel to the sample current. This phenomenon can be described by the chiral anomaly. The oscillations of magnetoresistance, which happens when we apply a magnetic field perpendicular to the sample current, can be explained by discrete scale invariance in topological materials. According to our experimental results, we know that Te has properties of Weyl materials and can be used to study physics about Weyl materials. | en |
