研究成果

從事材料輻照損傷研究工作。 在輻照損傷和熱年代學交叉方向的系統研究被裂變徑跡領域權威Andrew Gleadow院士評價為“對基本徑跡結構理解的非常重大進展”，“代表了這種背景下的巨大進步”。 通過鑽石刀製備透射電鏡樣品，觀察到未腐蝕裂變徑跡整個長度上每一點的輻照損傷及熱退火情況，被EPSL審稿人Trevor Dumitru博士署名評價為“標定套用廣泛的‘裂變徑跡熱年代學’體系中的一個非常重要的技術突破”。 截至2015年10月，共發表論文30多篇，其中SCI索引論文26篇，專利1項。 目前是Scientific Reports, Contributions to Mineralogy and Petrology, Physics and Chemistry of Minerals, Journal of Materials Chemistry, Applied Physics Letters等16個國際期刊審稿人。

學術貢獻

1.發現磷灰石和鋯石裂變徑跡的不同結構，為理解兩種材料中諸多不同行為提供了新的線索，為Shuster等人的輻照損傷‘束縛’模型提供了有力支持。
2.觀察到裂變徑跡的退火動態過程，為揭示磷灰石和鋯石不同的退火機理提供最“直接”證據。
3.觀察到整個裂變徑跡長度，並發現裂變徑跡退火速度隨裂變半徑的減小而加快的現象，為今後退火模型指明了方向。
4.證實核徑跡半徑大小與晶體方位無關，為退火方位效應提供了解釋。

研究方向

礦物輻照損傷在熱年代學的套用，離子與固體相互作用，材料輻照效應
