Andrea Cavalleri,Robert W. Schoenlein Die Randbedingung lautet demnach hier .. = 0, wenn der Index 5 die Zustände hinter dem reflektierten Stoß charakterisiert. Für diesen reflektierten Stoß gelten wieder die Gl. (17) bis (21), nur eben mit der Randbedingung .. = 0, d. h., die Nachströmgeschwindigkeit .. bezüglich des mit .. laufenden Systems, muß gleich —.. sein.冷淡周边 发表于 2025-3-27 04:10:18

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 exactlOriginal 发表于 2025-3-27 13:38:45

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.

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 2DMEN 发表于 2025-3-28 02:27:43
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执拗 发表于 2025-3-28 08:00:03
