The level structure of 25 Al has been studied at the ORNL Holifield Radioactive Ion Beam Facility (HRIBF) by measuring the angular and energy distributions of alpha particles from the 28 Si(p,α) 25 Al reaction. Proton beams (~10 nA) at laboratory energies of 40-and 42-MeV were generated by the 25 MV tandem accelerator and bombarded a natural silicon target (50 µg/cm 2). Alpha particles were det...
In this paper, an electrical-based NH₃ sensor with an Al/p-Si/Al structure is reported. The p-Si substrate is microstructured by fs-laser irradiation and then etched by 30% alkaline solution. This sensor works well at room temperature with fast response/recovery for NH₃ gas at 5-100 ppm concentration. However, when the sensor is annealed in N₂/H₂ forming gas or short-circuited for Al/Si electro...
