Thermosensation01:43

Thermosensation

29.7K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

G-Protein Gated Ion Channels

5.4K
GPCRs are primarily responsible for our sense of smell, taste, and vision.  The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.

Summary

Researchers studied the photoresponse in gapped bilayer graphene using optical and transport measurements. They found identical bolometric and photovoltaic response times, indicating hot electron thermal relaxation governs both, with response times around 20-100 ps.

Area of Science:

  • Condensed matter physics
  • Materials science
  • Optoelectronics

Background:

  • Gapped bilayer graphene exhibits unique electronic properties.
  • Understanding photoresponse mechanisms is crucial for optoelectronic applications.

Purpose of the Study:

  • Investigate the photovoltaic and bolometric photoresponse in gapped bilayer graphene.
  • Determine the response times and underlying mechanisms.

Main Methods:

  • Utilized optical and transport measurements.
  • Employed a pulse coincidence technique at 1.5 μm.
  • Measured photoresponse as a function of temperature.

Main Results:

  • Identical response times for bolometric and photovoltaic effects were observed.
  • Response times ranged from approximately 20 to 100 picoseconds (ps) across temperatures from 3-100 K.
  • Above 10 K, the relaxation time remained constant at 25 ± 5 ps, independent of temperature.

Conclusions:

  • The photovoltaic response in gapped bilayer graphene is governed by hot electron thermal relaxation.
  • The findings provide insights into the ultrafast dynamics of photogenerated carriers.
