摘要： The present invention provides instruments and methods for screening combinatorial libraries that addresses many of the problems encountered when using conventional instruments. For example, the disclosed instruments can measure mechanical properties of library members in rapid serial or parallel test format, and can perform tests on small amounts of material, which are easily prepared or dispensed using art-disclosed liquid or solid handling techniques. Compared to conventional instruments, the disclosed instruments afford faster sample loading and unloading, for example, through the use of disposable libraries of material samples.

摘要： An apparatus and method for screening combinatorial libraries of materials by measuring the response of individual library members to mechanical perturbations is described. The apparatus generally includes a sample holder for containing the library members, an array of probes for mechanically perturbing individual library members, and an array of sensors for measuring the response of each of the library members to the mechanical perturbations. Library members undergoing screening make up a sample array, and individual library members constitute elements of the sample array that are confined to specific locations on the sample holder. During screening, the apparatus mechanically perturbs individual library members by displacing the sample array (sample holder) and the array of probes. Typically, all of the elements of the sample array are perturbed simultaneously, but the apparatus also can also perturb individual or groups of sample array elements sequentially. The flexible apparatus and method can screen libraries of materials based on many different bulk physical properties, including Young's modulus (flexure, uniaxial extension, biaxial compression, and shear); hardness (indentation), failure (stress and strain at failure, toughness), adhesion (tack, loop tack), and flow (viscosity, melt flow indexing, and rheology), among others.

摘要： A process for synthesizing wide band gap materials, specifically, GaN, employs plasma-assisted and thermal nitridation with NH.sub.3 to convert GaAs to GaN. Thermal assisted nitridation with NH.sub.3 can be employed for forming layers of substantial thickness (on the order of 1 micron) of cubic and hexagonal GaN on a GaAs substrate. Plasma-assisted nitridation of NH.sub.3 results in formation of predominantly cubic GaN, a form particularly useful in optoelectronic devices. Preferably, very thin GaAs membranes are employed to permit formation thereon of GaN layers of any desired thickness without concern for critical thickness constraints. The thin membranes are preferably formed either with an epitaxial bonding technique, or by undercut etching.
