Summary: The photo‐crosslinking of carbazole dendrimers was analyzed by UV and IR spectroscopic methods. Photoirradiation results in the formation of a film that is insoluble in toluene and benzene. Time‐of‐flight mass spectrometry studies revealed that the photoirradiation lead to an oligomerization of the dendrimer through crosslinking. The resulting insoluble dendrimer film could be applied as a hole‐transport layer in efficient polymer electroluminescence devices (PLEDs).

STT efficiency of p-MTJs with the free layer diameter d from 10 to 30 nm was evaluated using LLG micro-magnetic simulation. The STT efficiency for MTJs with the etch-damaged sidewall increases with a decrease in d, which is different from that without the damage. The STT efficiency for MTJs with the conical shape slightly decreases with a decrease in d.
