Graphene nanoribbon (GNR) has possibility to overcome the carbon nanotube chirality challenge as a nanoscale device channel. Because of one dimensional behavior of GNR, carrier statistic study is attractive. More research work has been done on carrier statistic study of GNR especially in Boltzmann approximation (Nondegenerate regime). Based on quantum(More)
Ohm's law, a linear drift velocity response to the applied electric field, has been and continues to be the basis for characterizing, evaluating performance, and designing integrated circuits, but is shown not to hold its supremacy as channel lengths are being scaled down. In the high electric field, the collision-free ballistic transport is predicted,(More)
Recent development of trilayer graphene nanoribbon Schottky-barrier field-effect transistors (FETs) will be governed by transistor electrostatics and quantum effects that impose scaling limits like those of Si metal-oxide-semiconductor field-effect transistors. The current-voltage characteristic of a Schottky-barrier FET has been studied as a function of(More)
The potential uses of Pandanus amaryllifolius leaf extract as a natural antioxidant were evaluated in refined, bleached and deodorized (RBD) palm olein, using accelerated oxidation and deep frying studies at 180°C from 0 to 40h. The extracts (optimum concentration 0.2%) significantly retarded oil oxidation and deterioration (P<0.05), comparably to 0.02% BHT(More)
A process of making a symmetrical self-aligned n-type vertical double-gate MOSFET (n-VDGM) over a silicon pillar is revealed. This process utilizes the technique of oblique rotating ion implantation (ORI). The self-aligned region forms a sharp vertical channel profile and decreases the channel length Lg. A tremendous improvement in the drive-on current is(More)
Several million tones of palm oil and palm olein are used annually in the world for frying. This paper will discuss their frying performances in three major applications - industrial production of potato chips/crisps, industrial production of pre-fried frozen French fries and in fast food outlets. In the first study, about four tones of potato chips were(More)
Understanding of quantum limit in low dimensional devices helps to develop the new device types same as Carbon Nanotube Field Effect Transistor (CNTFET) and Naonowire. For each dimensionality the limitations on carrier drift velocity due to the high-field streaming of otherwise randomly velocity vector in equilibrium is reported. The results are based on(More)
