The invention is a simple method to fabricate multiple layers of transistors with one on top of each other in a 3D structure. Compare with some of the current practice, the new method is simple, flexible, controllable and capable to form much better performance transistors. The use of Metal-Induced.....

Almost all soil slopes on land are initially unsaturated in nature. In order to determine the factor of safety of unsaturated slopes accurately, it is essential to calculate transient seepage and hence pore water pressures in the soil. To do so, one has to measure the so-called soil-water characteri.....

Display is a large and still continuously expanding market. Flat-panel display is the dominating segment in the industry which involves the use of active-matrix driving technology. In conventional active matrix displays, thin film transistors (TFTs) are formed by amorphous silicon (a-Si). However, i.....

Electrorheological(ER) fluids are of high interest because potentially they can provide simple, quiet, and fast interfaces between electrical controls and mechanical systems. However, a problem with ER fluids to date is that the yield strength is too low for many practical applications. The main dra.....

A laser interferometer system can be used to measure the straightness of an object. A typical Hewlett-Packard's straightness interferometer system uses a Wollaston prism to split a laser beam traveling along a principal axis into two secondary beams. However, the resolution and the range of the resp.....
