Micro-thermocouple on nano-membrane: thermometer for nanoscale measurements

A luminescent molecular thermometer for long-term absolute temperature measurements at the nanoscale.

Current developments [ 4 ] of thermometers operating below a few micrometers and with high spatial resolution include: Ga-fi lled carbon/MnO nanotubes, [ 2 ] temperature-dependent conformation modifi cations of molecular spring superstructures, [ 3 ] Raman [ 10 ] and infrared [ 11 ] spectroscopic probing, scanning thermal microscopy probes, [ 6 ] and luminescence-based measurements.

Probing Maxwell's demon with a nanoscale thermometer.

A precise definition for a quantum electron thermometer is given, as an electron reservoir coupled locally (e.g., by tunneling) to a sample, and brought into electrical and thermal equilibrium with it. A realistic model of a scanning thermal microscope with atomic resolution is then developed, including the effect of thermal coupling of the probe to the ambient environment. We show that the tem...

Development of a low-cost micro-CMM for 3D micro/nano measurements

A high-precision and low-cost micro-CMM (coordinate measuring machine) is under development. The expected measuring range is 25 × 25 × 10 mm3 and the resolution is 1 nm. In order to enhance the structural accuracy, some new ideas are integrated into the design, such as the arch-shape bridge for better stiffness and thermal accuracy, and the co-planar stage for less Abbe error. The linear diffra...

Ventilation effects on humidity measurements in thermometer screens

Relative humidity (RH) measurements, as derived from wet-bulb and dry-bulb thermometers operated as a psychrometer within a thermometer screen, have limited accuracy because of natural ventilation variations. Standard RH calculations generally assume a fixed screen psychrometer coefficient, but this is too small during poor ventilation. By comparing a reference humidity probe—exposed within a s...
