This brief deals with the impact of spin-transfer torque magnetic random access memory (STT-MRAM) cell based on double-barrier tunnel junction (DMTJ) performance a two-layer multilayer perceptron (MLP) neural network. The DMTJ-based is benchmarked against conventional single-barrier MTJ (SMTJ) counterpart by means comprehensive evaluation carried out through state-of-the-art device-to-algorithm...

N-face AlGaN (cap)/GaN (channel)/AlGaN (barrier)/GaN (buffer) high electron mobility transistors (HEMTs) provide a simple solution for strong confinement of the two-dimensional electron gas (2DEG) from the back since carriers are induced on top of the AlGaN barrier. To reduce the adverse effects of random alloy scattering from the AlGaN barrier, an N-face GaN-spacer HEMT was designed with an ep...

We use two heterostructure designs to improve the energy conversion efficiency of solidstate thermionic devices. The first method is to use a non-planar heterostructure with roughness in order of electron mean free path. This has some combined benefits of increased effective interface area, and reduced total internal reflection for the electron trajectories arriving at the interface. Monte Carl...

Immune cell trafficking requires the frequent breaching of the endothelial barrier either directly through individual cells ('transcellular' route) or through the inter-endothelial junctions ('paracellular' route). What determines the loci or route of breaching events is an open question with important implications for overall barrier regulation. We hypothesized that basic biomechanical propert...

This work describes the simulation and modeling of current voltage characteristics of polymer light emitting diode. To understand the device characteristics first a single layer organic device with single carrier injection is studied. The simulations are used to clarify the role of barrier height, device thickness and mobility. A new analytical model is developed based on a simple mobility mode...

Barrier options are cheaper than the respective standard European options, because a zero payoff may occur before expiry time T. Lower premiums are usually offered for more exotic barrier options, which make them particularly attractive to hedgers in the financial market. Under the Black-Scholes framework, we explicitly derive and present pricing formulae for a range of different European barri...
