I had proposed new methods for synthesizing novel molecular crystals: transient metal (TM) peroxide/superoxide, which had never found in the crust of Earth. I am interested in novel electric functions based on spin-orbital interactions of 4d or 5d TM and first I tried to synthesize both bulk and thin films by the reaction between (1) reduced oxygen molecules (O-O-) and 4d/5d TM and (2) oxygen plasma (O-O+) and 4d/5d TM, however, no novel materials were obtained. I discussed in parallel on the introduction of peroxide anions over the TM surface by the deep-UV light irradiation and this process would partially succeeded. A TM oxide heterojunction device were manufactured and its novel functions, photo-induced charge transfer between aromatic VOC (Volatile Organic Compound) adsorbate and peroxide anions. Novel gas sensing properties were found out in the system NiO-ZnO, which will be applicable for high-performance VOC sensors.

我提出了合成新型分子晶体的新方法：瞬时金属（TM）过氧化物/超氧化物，这些金属（TM）在地壳中从未发现过。我对基于4D或5D TM的自旋轨道相互作用的新型电函数感兴趣，首先，我试图通过（1）（1）减少氧分子（O-O-）和4D/5D TM和（2）氧气等离子体（O-O-O+）（O-O+）以及4D/5D TM的反应来合成散装和薄膜。我同时讨论了通过深紫外光照射在TM表面引入过氧化物阴离子的引入，该过程将部分成功。制造了TM氧化物异质结和其新功能，芳族VOC（挥发性有机化合物）吸附物和过氧化物阴离子之间的光诱导电荷转移。在系统Nio-Zno中发现了新型的气体传感特性，该特性将适用于高性能VOC传感器。
