Ultrafast Scanning Tunneling Microscopy: Principles and Applications,c scale. We describe here approaches for ultrafast STM based on photoconductive gating ultrafast STM, time-resolved STM through tunnel-distance modulation, and ultrafast junction-mixing STM.While much progress has been made to develop these techniques and understand both their limitations and exactl

Spontaneous Emission from Semiconductors After Ultrafast Pulse Excitation: Theory and Simulation,nals for arbitary nonequilibrium situations. In combination with quantum-kinetic simulations of electron--hole-pair generation and relaxation, this theory is then applied to the calculation of hot-luminescence signals from pulse-excited semiconductors. The numerical simulations for bulk GaAs show ho

Carrier Dynamics in III--Nitrides Studied by Time-Resolved Photoluminescence,ent. Similar results have been obtained for InAlGaN-based QWs. Studies on AlGaN/GaN heterostructures with high Al content show that the PL emission lines associated with a two-dimensional electron gas (2DEG) persist at temperatures up to ., in sharp contrast to the AlGaAs/GaAs system in which the 2D

Femtosecond X-Rays and Structural Dynamics in Condensed Matter,n storage rings, achieved by interaction of femtosecond optical pulses and picosecond-long electron bunches within an insertion device (wiggler). The primary advantage of these new schemes, producing trains of pulses that are comparable in photon numbers to laser-produced plasma sources, is the tuna
