Title
Magnetic field dependence of terahertz emission from an optically excited GaAs p-i-n diode
Output type: Journal article
Journal title: PHYSICAL REVIEW B
Month/year of publication: August 2002
Pagination: 085307-1-085307-8
Volume: 66 (8)
ISSN: 0163-1829
DOI: 10.1103/PhysRevB.66.085307 ?
Co-authors: Armitage A, Huggard PG, Shaw CJ
Number of additional co-authors: 2
Other relevant details: First quantitative theoretical and experimental description of the effect of magnetic fields on THz emission in optically excited semiconductors. Showed that it is not possible to generate more THz power by application of a magnetic field (as was previously suggested). Andrews conceived and led the project.
