Abstract
Photodiode‐type solar‐blind photodetectors (SBPDs) with the self‐powered feature hold great promise for applications in unattended secure communication, flame detection, and missile warning. However, the responsivity of SBPDs is usually ...
In this paper, we present the observation results of the surface potential of micropatterned thick (>1 & mu;m) self-assembled electrets (SAEs) for MEMS vibrational energy harvesters (VEHs). To evaluate the surface potential of micropatterned SAEs,...
1,3,5,7-Tetrakis(1-phenyl-1H-benzo[d]imidazol-2-yl)adamantane exhibits large and stable surface orientation polarization in vacuum-deposited films due to the subtle orientation selectivity of the molecule and the non-conjugated adamantane core.
