| Description
| - Visible Scanning Near Field Optical Microscopy (SNOM) was used to study cleaved edges of GaAs solar cell devices. SNOM is a relatively new technique that combines the versatility of optical microscopy with the resolution of a scanning probe microscope. Light coupled into a tapered optical fiber is used for excitation. The fiber probe is scanned over the sample while being held ~10 nm above the surface. At this point, any number of high resolution (~100 nm) optical measurements can be made. In this work, we measured the NSOM-induced photocurrent in GaAs devices. Our goal was to obtain spatially resolved measurements of the photocurrent response across the various layers in crystalline GaAs solar cells, by studying the cleaved edges of the cells. For excitation energies well above the bandgap, carrier recombination at the cleaved surface had a strong influence on the photocurrent signal. Decreasing the excitation energy, which increased the optical penetration depth, allowed the effects of su

- Rastrovací optická mikroskopie v blízkém poli ve viditelné oblasti je relativně nová technika, která kombinuje všestrannost optického mikroskopu s rozlišením sondových mikroskopů. Světlo vevázané do hrotu optického vlákna excituje vzorek a je možné je použít ke spektroskopickým měřením. Zde je použito k meření SNOM indukovaného fotoproudu na GaAs součástkách. Cílem je dosáhnout měření odezvy fotoproudu různých vrstev krystalického GaAs slunečního článku s vysokým prostorovým rozlišením. K tomu se použžívá měření na hranách zlomu článků. (cs)
