| 2 | Self-generating nanogaps for highly effective surface-enhanced Raman spectroscopy显示文摘The fabrication of surface enhanced Raman spectroscopy(SERS)substrates with controlled high density hot spots still remains challenging.Herein,we report highly effective SERS substrates containing the self-generating(SG)nanogaps from polystyrene nanosphere monolayer through isotropic plasma etching.The emergence of multimode hot spots,i.e.,metal film over nanosphere(MFON)-like hot spots(closed gaps,0 nm),individual self-aligned hot spots(discrete gaps,>20 nm)and threedimensional(3D)hot spots(nanogaps,1-10 nm),makes the SG SERS substrates superior as compared to the traditional MFON or the well-ordered self-aligned SERS substrates in terms of enhancement,uniformity,and reproducibility.The SG SERS substrates can function as the excellent SERS platforms for trace molecule detection in the practical application fields. | Yangkai Chen Huan Li Jianmei Chen Dong Li Mengyuan Zhang Guanghua Yu Lin Jiang Yi Zong Bin Dong Zhoufang Zeng Yandong Wang Lifeng Chi | 2022 | Nano Research2022，15，4： | 1 |
| 3 | Influence of SAM Quality on the Organic Semiconductor Thin Film Gas Sensors显示文摘Gas sensors based on organic semiconductors receive tremendous attentions owing to their advantages on high selectivity and room temperature operation. However, until now, most organic semiconductor based sensors still suffered from problems, such as low sensitivity, slow response/recovery speed and poor stability. In addition, a clear correlation between the sensing performance and the film property is still absent. Herein, we report the investigation on sensing performance of a series of organic films with various morphologies. By simply adjusting the quality of self-assembled monolayer(SAM) on the silicon wafer surface, we obtain organic semiconductor 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) films with varied morphologies and different charge transport abilities. The film with a small grain size and a continuous morphology presents the highest sensing performance to NO2, with a sensitivity up to 730%/ppm(ppm=parts per million, vo-lume ratio). We thus reveal that the high sensitivity of the organic film is evident related with the charge transport ability and initial conductivity of the films, as well as the morphologies of both modification layer and the active films. | ZHU Lunan WANG Zi LU Jie ZHOU Xu ZENG Zhoufang HUANG Lizhen CHI Lifeng | 2022 | Chemical Research in Chinese Universities2022，38，2： | 0 |
