Micro-Raman thermography approaches normally use below-bandgap probe light sources and would underestimate channel temperatures. Commercial thermoreflectance reflectance imaging (TTI) techniques ...

There is growing evidence that phonon-polariton interactions can occur at interfaces involving 2D van der Waals ... A mid-infrared probe beam with a diameter of 200 μm was focused onto the same pad to ...

Newly published research in the journal Nature demonstrates a new way of generating long-wave infrared and terahertz waves. The work 'Hyperbolic phonon-polariton electroluminescence in 2D ...

为解决声子极化激元（Phonon polaritons）激发难题，研究人员发现其可电激发，有望用于光电器件。 声子极化激元（Phonon polaritons）是光子与极性电介质中光学声子相干耦合产生的准粒子。因其能将电场限制在深亚波长尺度且损耗低，在超衍射成像、近场能量转移 ...

Phonon-polaritons are a unique type of electromagnetic wave that occurs when light interacts with vibrations in a material's crystal lattice structure. These phonon-polariton waves exhibit several ...

These phonon-polariton waves exhibit several unique characteristics. For example, they can concentrate the energy of long-wavelength infrared light into extremely small volumes, even down to tens ...
