The effect of hydrogen on the electroforming of thin films of RF-sputtered Pr0.7Ca0.3MnO3 (PCMO) was studied. We sputtered a series of samples with 0% to 5% H2 in the 9:1 Ar:O2 sputtering plasma. During constant-voltage forming, a large transient current was observed in the samples sputtered in H-containing plasma. The integrated charge of this step response correlates with the signal intensity of...
Summary form only given. A scaled two-dimensional particle-in-cell model of a planar DC sputtering magnetron is developed using the XOOPIC code1. The PIC model includes collisions through a Monte Carlo model, and includes the ability to calculate spatial, energy, and angular distribution functions for ions impacting arbitrary surfaces. Due to the large computational expense as well as a physical instability...
One of the main materials issues present in the ITER current design is the formation of mixed materials in the divertor region. Presently, the component where most of the energy is deposited in the ITER divertor are the vertical inboard and outboard plates, which are to be manufactured with composite carbon fiber (CFC) according to the latest design. The first wall, on the other hand, has beryllium...
