Thermal quenching of thermally stimulated conductivity

Journal of Physics D: Applied Physics, 1994
Thermal quenching of thermally stimulated conductivity has been considered theoretically assuming a model with three types of states in the bandgap of a semiconductor. It has been shown that the contribution of minority charge carriers to thermally stimulated conductivity might distort the shape of a peak or even change the number of peaks observed ...

Thermal Sensation on Forehead Using Electrical Stimulation

Extended Abstracts of the 2021 CHI Conference on Human Factors in Computing Systems, 2021
Thermal sensation systems are embedded into head-mounted displays using Peltier devices, water, or chemical substances to enhance the sense of presence in virtual reality environments. We propose a new method of presenting thermal sensation to the forehead by using electrical stimulation. This is based on our finding that when electrical stimulation is

Thermally stimulated creep

Journal of Electrostatics, 1977
Abstract We propose a new method for the investigation of molecular movements in solids: in a mechanical step-function experiment, we thermally stimulate the response to a given frozen-in stress (or strain). The high resolving power of this technique enables a detailed study of the complex retardation (or relaxation) modes observed in polymers ...

The relationship between thermally stimulated luminescence and thermally stimulated conductivity

British Journal of Applied Physics, 1967
If the recombination lifetime is a rapid function of temperature, thermally stimulated luminescence and conductivity are not related by a constant scale factor. It is thus not permissible to assume that the published theory describes both cases. This is discussed with particular reference to the theory of Garlick and Gibson.

Thermally stimulated current of solid pullulan

Journal of Macromolecular Science, Part B, 1983
Pullulan is used as food material and as food packaging films. Nevertheless, its physical properties have not been investigated in detail. In order to develop further utilization (1), it is desirable to know the relation between its chemical structure and physical properties.

Thermally Stimulated Luminescence of Irradiated Caffeine

International Conference on Luminescence - 1984, 1984
This study is part of a continuing investigation of the factors which affect radiation damage in methylxanthines, which are of immense biomedical importance. In order to gain knowledge regarding charge trapping mechanisms in caffeine (1,3,7-trimethylxanthine) we employed the well-known technique of thermally stimulated luminescence (TSL) and ...

A comment on thermally stimulated polarisation currents

Journal of Physics C: Solid State Physics, 1978
The theory of thermally stimulated polarisation current is presented. Mathematical solutions for the transient regime are established taking into account the temperature dependence of saturation polarisation in agreement with the Langevin formula. Computed solutions differ from the calculations of McKeever and Hughes (J. Phys.

Corneal pain evoked by thermal stimulation

Pain, 1979
The thermal sensitivity of the eyelid and cornea was compared using an automated apparatus to produce stimulus pulses of known magnitude and duration over the range 33--45 degrees C. Subjects reported only temperature sensation when the skin of the upper eyelid was tested; however, corneal stimulation in the same subjects was always perceived as ...

Controllable release from magnetoliposomes by magnetic stimulation and thermal stimulation

Colloids and Surfaces B: Biointerfaces, 2013
Liposomes with superparamagnetic iron oxide nanoparticles embedded in membrane were prepared by the supercritical carbon dioxide (scCO(2)) method. The cargos can be released from liposomes by both triggered agents, temperature and alternating current electromagnetic field (AMF). The release mechanism was explained from the view of microstructure change

Simultaneous measurement of thermally stimulated luminescence and thermally stimulated current of ZnSe single crystal

Journal of Physics D: Applied Physics, 1995
We have simultaneously measured the thermally stimulated current (TSC) and thermally stimulated luminescence (TSL) of two ZnSe single crystals grown by the sublimation method and have observed a peak conversion near 150 K. In order to identify the origin of such a peak conversion, we have also measured the negative thermally stimulated current (NTSC ...
