Photo-excited hot carrier dynamics in hydrogenated amorphous silicon imaged by 4D electron microscopy.
Charge carrier dynamics in amorphous semiconductors has been a topic of intense research that has been propelled by modern applications in thin-film solar cells, transistors and optical sensors. Charge transport in these materials differs fundamentally from that in crystalline semiconductors owing to the lack of long-range order and high defect density. Despite the existence of well-established...
متن کاملAtomistic simulation of light-induced changes in hydrogenated amorphous silicon
We employ ab initio molecular dynamics to simulate the response of hydrogenated amorphous silicon (a-Si:H) to light exposure (the Staebler– Wronski effect). We obtain improved microscopic understanding of photovoltaic operation, compute the motion of H atoms, and modes of lightinduced degradation of photovoltaics. We clarify existing models of lightinduced change in a-Si:H and show that the ‘hy...
متن کاملHydrogen dynamics and light-induced structural changes in hydrogenated amorphous silicon
We use accurate first-principles methods to study the network dynamics of hydrogenated amorphous silicon, including the motion of hydrogen. In addition to studies of atomic dynamics in the electronic ground state, we also adopt a simple procedure to track the H dynamics in light-excited states. Consistent with recent experiments and computer simulations, we find that dihydride structures are fo...
متن کاملUltrafast Dynamics of Photoexcited Carriers in HWCVD a-Si:H and a-SiGe:H
We present femtosecond studies of photoexcited carrier dynamics in hydrogenated amorphous silicon and silicon-germanium alloys grown by the hot-wire assisted chemical vapor deposition (HWCVD) technique, which is promising for producing high-quality device-grade materials. We have used wavelength-resolved femtosecond pump-probe techniques to study the dynamics of photoexcitations in these materi...
متن کاملStructural disorder induced in hydrogenated amorphous silicon by light soaking
We show, using variable coherence transmission electron microscopy, that light soaking of amorphous hydrogenated silicon thin films leads to structural changes. We speculate that the structural changes are associated with instability in the as-deposited material. We suggest that improved immunity to Staebler–Wronski degradation could be achieved by a less-ordered material which is closer to the...
