The first and second electrodes are capacitively coupled to each other to faciliate electrical communication between the electronic device layer (104, 204, 304, 404, 504) and the optical layer (108, 208, 308, 408, 508) through transmission of an electrical signal between the first and second electrodes. The electrical signal may be transmiited through the insulator layer (106, 206, 306, 406, 506). In additional, the electronic device layer (104, 204, 304, 404, 504 and the optical layer (108, 208, 308, 408, 508) may be in electrical communication with each other through capacitive coupling of the first electrode (110, 210, 410, 510) and the second electrode (112, 212, 412, 512).
Abstract:
A contact lithography apparatus (100,220), system (200) and method (300) use a deformation (320) to facilitate pattern transfer (300). The apparatus (100,220), system (200) and method 300 include a spacer (120,226) that provides a spaced apart parallel and proximal orientation 310 of lithographic elements, such as a mask (110,228a,222) and a substrate (130,228b,224), when in mutual contact with the spacer (120,226). One or more of the mask (110,228a,222), the substrate (130,228b,224) and the spacer (120,226) is deformable, such that deformation (320) thereof facilitates the pattern transfer (300).

Abstract:
A method of performing quantum well intermixing in a semiconductor device structure uses a sacrificial part of a cap layer, that is removed after QWI processing, to restore the cap surface to a condition in which high performance contacts are still possible. The method includes: a) forming a layered quantum well structure including a doped cap layer; b) forming an etch stop layer over said cap layer; c) forming a sacrificial layer over said etch stop layer, said etch stop layer having a substantially lower etch rate than said sacrificial layer when exposed to predetermined etch conditions; d) carrying out a quantum well intermixing process on the device structure, which process induces significant damage to at least a portion of the sacrificial layer; e) removing the sacrificial layer in at least a contact region of the device using an etch procedure selective against the etch stop layer to expose said etch stop layer in the contact region; and f) forming a contact over the layered quantum well structure in at least said contact region.

The olfactory sensing element has circuitry connected thereto for identifying amines characteristic of bacterial vaginosis. Means are provided for supplying vapours (2) from a sample (4) to the olfactory sensing element.
Abstract:
Apparatus for detecting the presence of volatile amines in a sample is disclosed. The apparatus has a receptacle (6, 40) containing a test composition. A swab (10, 16, 58) brings a sample into contact with the test composition and an indicator substance (30, 44) is arranged to detect vapour arising as a result of reaction of the sample with the test composition and to change colour if said vapour contains volatile amines. The apparatus can be used in the diagnosis of bacterial vaginosis.
Abstract:
Various embodiments of the present invention are directed to semiconductor light-emitting devices that provide energy efficient, high-speed modulation rates in excess of 10 Gbits/sec. These devices include a light-emitting layer embedded between two relatively thicker semiconductor layers. The energy efficient, high-speed modulation rates result from the layers adjacent to the light-emitting layer being composed of semiconductor materials with electronic states that facilitate injection of carriers into the light-emitting layer for light emission when an appropriate light-emitting voltage is applied and facilitate the removal of carriers when an appropriate light-quenching voltage is applied.
