俄罗斯莫斯科师范大学和美国罗切斯特大学的科学家共同设计出了能测量红外线光子能量的探测器。该探测器的主要部件为一块处于低温超导状态的硝酸铌薄膜。在这种薄膜的结晶点阵中,惟一处于活跃状态的是电子。当波长为3至10微米的单个红外线光子进入结晶点阵后,其能量会被电子吸收和传递,从而形成一个串联电路。 Russia's Moscow Normal University and the University of Rochester scientists have jointly designed a detector that measures the energy of infrared photons. The main part of the detector is a niobium nitrate thin film in a cryogenic superconducting state. In the crystalline lattice of this film, the only active state is the electron. When a single infrared photon with a wavelength of 3 to 10 microns enters the crystal lattice, its energy is absorbed and transferred electronically, forming a series circuit.
