Abstract: The present invention is directed to a device comprising an epitaxial structure comprising a superlattice structure having an uppermost 2DxG channel, a lowermost 2DxG channel and at least one intermediate 2DxG channel located between the uppermost and lowermost 2DxG channels, source and drain electrodes operatively connected to each of the 2DxG channels, and a plurality of trenches located between the source and drain electrodes. Each trench has length, width and depth dimensions defining a first sidewall, a second sidewall and a bottom located therebetween, the bottom of each trench being at or below the lowermost 2DxG channel. A crenelated gate electrode is located over the uppermost 2DxG channel, the gate electrode being located within each of the trenches such that the bottom surface of the gate electrode is in juxtaposition with the first sidewall surface, the bottom surface and the second sidewall surface of each of said trenches.

Abstract: Methods and systems for assessing and tracking operational and functional performance can include compiling performance data for an entity (e.g., an entire enterprise, a corporate business unit, a particular operational region, a particular position, a particular employee, etc.) corresponding to a plurality of indicators corresponding to at least one goal category. The method may further include weighting the performance data corresponding to the plurality of indicators for the entity and generating a performance score for the entity based on the weighted or un-weighted performance data. Another method for assessing performance of at least one entity can be based on a first set of indicators and a second set of indicators reflecting performance of the entity.

Abstract: A method and system for evaluating internal business investments by estimating decision-factor variations provides a powerful decision-making tool for deciding whether or not to invest in a particular internal business option or for selecting between business investment alternatives. The investment may be a capital investment, a program investment, personnel investment or other business strategy. Variations in cost, benefit, strategic alignment and risk values input to the business decision tool are used to adjust the business value of a business case. The variations can be estimated from data gathered from surveys of personnel rating a confidence or perceived variation from the input values, variations may be estimated in the computed business value due to interdependencies to other adopted or non-adopted business cases, or variations may be estimated based on actual historical collected data on business case performance.
