O'Connor, Thomas P. (1977)Ferroelectric crystals show an unexpected T³ᐟ² term in the specific heat. An experiment is discussed, as well as background information on ferroelectrics and specific heats, in which the thermal expansion coefficient is ...
-
Prater, Craig B. (1987)This paper examines the feasibility of using a cryogenic optical fiber link for an irradiation study of the quantum Hall effect (QHE). Commercially available GaAs₁₋ₓPₓ light-emitting diodes (LED's) were studied at temperatures ...

Weichold, Mark H.; Kinard, William B.; Kirk, Wiley P. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1992-03-03)A gated resonant tunneling diode has a semiconductor mesa formed on a semiconductor substrate, a tunneling barrier layer between the mesa and the substrate, and a gate layered over the substrate about the mesa and aligned ...

DeJongh, Erik E. (1993)In this thesis, transport in Bipolar Quantum Resonant Tunneling Transistors (BiQuaRTTs) is studied. A ⁴He cryostat was built, and ³He- ⁴He dilution refrigerator was modified for this work. Preliminary results in these ...

Ham, Thomas Edwar (Texas A&M University. Libraries, 1984)Ginzburg-Landau theory is used to investigate states in which both superconductivity and ferromagnetism exist simultaneously in certain rare-earth ternary compounds. The "spontaneous vortex state" of Kuper, Revzen and Ron ...

Kirk, Wiley P.; Zhou X, Joe; Gnade, Bruce E.; Cho, Chih-chen (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2002-07-16)A method of forming lattice matched single crystal wide bandgap II-VI compound semiconductor films over a silicon substrate includes first cleaning (10) the silicon substrate. A passivation layer is formed (18), which may ...
-
Andrews, Craig Collin (Texas A&M University. Libraries, 1993)A transmission electron microscope has been converted for electron beam lithography applications where computer control of the stage and electron beam are required. Supporting modifications and extensive software complete ...
-
Chesire, Daniel Patrick (Texas A&M University. Libraries, 1981)Measurements of the electrical resistivity, and both static and isoelectric thermopower have been made on a fine Au wire containing 1 ppm Fe over a range of temperatures between 7 K and 24 mK. A shallow minimum at higher ...

Early, Edward A. (1984)Several processes are candidates for use in a microminiature cryocooler. They are an adiabatic demagnetization cycle, a surface heat pumping cycle, and a cycle based on Joule-Thomson expansion. The later is chosen for ...
