A negatively charged oxide-nitride-oxide stack for field-effect passivation of crystalline silicon solar cells is discussed. The negative charge was injected into the stack by a plasma charge injection technology. Charge stability was studied by expo

The plasma charge injection technology reported earlier can be a low-cost alternative to the Al 2 O 3 passivation technology. The charge stability under sunlight exposure is a key concern. We investigated the light-induced loss of injected charge for

A novel terminally crosslinked block SPES-b membrane was prepared using an azide-assisted thermal curing of sulfonated multiblock poly(arylene ether sulfone). The membrane morphologies and conductivities were investigated as a function of temperature

The effect of annealing conditions for rapid thermal process on the electrical properties of BST thin films was investigated. RTN annealing was very effective for crystallization, however leakage current property was severely degraded due to the loss

We demonstrated a significant charge loss by a small DC bias applied to the SONOS gate. This charge loss can be correlated with that of a high-temperature bake. A bias acceleration test can be useful for wafer-level retention screening. The results a
