35 1674. Deep uv lithography. (USA) Using deep uv light ranging from 2000 to 2600 A, submicrometer patterns in photoresist with height-to-width aspect ratios as high as 15 can be achieved. The well known electron-beam positive resist, polymethyl methacrylate (PMMA), is used as the deep uv photoresis
Electronic structure and optical properties of CuGaS 2 are calculated using the full potential linearized augmented plane wave plus local orbitals method. The calculated equilibrium lattice is in reasonable agreement with the experimental data. The electronic structures indicate that CuGaS 2 is a se
## Abstract The absorption and reflection spectra of βgreenβ and βorangeβ CuGaS~2~ crystals, prepared by chemical transport reaction, have been studied at low temperatures. The βorangeβ crystal presents an excitonic spectrum characteristic for intrinsic material. The triplet structure can be explai
