Vacuum ultraviolet photoabsorption spectroscopy of space-related ices: Formation and destruction of solid carbonic acid upon 1~keV electron irradiation
S. Ioppolo, Z. Kanuchová, R. L. James +7
Carbonic acid (H2CO3) is a weak acid relevant to astrobiology which, to date, remains undetected in space. Experimental work has shown that the beta-polymorph of H2CO3 forms under…
Study of phonons in irradiated epitaxial thin films of UO
S. Rennie, E. Lawrence Bright, J. E. Darnbrough +6
We report experiments to determine the effect of radiation damage on the phonon spectra of the most common nuclear fuel, UO. We have irradiated thin ( 300 nm) epitaxial f…
Desorption of hot molecules from photon irradiated interstellar ices
J. D. Thrower, D. J. Burke, M. P. Collings +10
We present experimental measurements of photodesorption from ices of astrophysical relevance. Layers of benzene and water ice were irradiated with a laser tuned to an electronic tr…
Vertical transport and electroluminescence in InAs/GaSb/InAs structures: GaSb thickness and hydrostatic pressure studies
M. Roberts, Y. C. Chung, S. Lyapin +3
We have measured the current-voltage (I-V) of type II InAs/GaSb/InAs double heterojunctions (DHETs) with 'GaAs like' interface bonding and GaSb thickness between 0-1200 Å. A negati…
Metal-Insulator oscillations in a Two-dimensional Electron-Hole system
R. J. Nicholas, K. Takashina, M. Lakrimi +6
The electrical transport properties of a bipolar InAs/GaSb system have been studied in magnetic field. The resistivity oscillates between insulating and metallic behaviour while th…
