Double Printing nPERT Cells with Narrow Contact Layers

Freeze out in narrow and wide layers

The freeze out of particles from a layer of finite thickness is discussed in a phenomenological kinetic model. The proposed model, based on the Modified Boltzman Transport Equation, is Lorentz invariant and can be applied equally well for the freeze out layers with space-like and time-like normal vectors. It leads to non-equilibrated post freeze out distributions. The dependence of the resultin...

Hydraulically actuated micro-contact printing engines

Micro-contact printing (μCP) is a rapid, simple and well-established method of microscale biochemical patterning. However, there is a lack of inexpensive and accessible tools for accurately controlling contact during the printing process. In this paper, controlled μCP using hydraulic actuation is demonstrated. Complete printing systems, including a substrate placed at a calibrated height above ...

Filamentary double layers

The properties of double layers produced in current filaments have been studied. The experiments were performed in a magnetized triple plasma device in which the diameter of the central plasma column could be varied. The scaling of the double layer potential drop I’,, with the parameter jd’, where j is the current density in the double layer and d is the double layer thickness, was determined f...

Inkjet Printing of Isolation Layers for Back-Contacted Silicon-Heterojunction Solar Cells

For wafer based silicon solar cells, the combination of amorphous/crystalline silicon (a-Si:H/c-Si) heterojunction emitters (SHJ) [1] and back-contacted back-junction solar cell concepts (BCBJ) [2] offer a very high efficiency potential of around 24%. Stangl et al. proposed a relatively simple and therefore attractive cell concept comprising a two level metallization isolated by an insulation l...
