Abstract

By means of terahertz and infrared (THz, IR) spectroscopies we have measured the dielectric response of nano-filaments of electrogenic bacteria Shewanella oneidensis MR-1 in a wide frequency and temperature ranges. THz-far-IR spectra are dominated by absorption due to bound water. At helium temperatures and at sub-THz frequencies a boson-peak-like excitation is detected that is typical for disordered materials. The observation is in agreement with the heat capacity measurements.

细菌纳米丝的太赫兹和红外光谱
利用太赫兹和红外光谱(THz, IR)测量了产电细菌希瓦氏菌MR-1纳米细丝在宽频率和宽温度范围内的介电响应。太赫兹-远红外光谱主要是由于结合水的吸收。在氦温度和次太赫兹频率下,可以探测到一种玻色子峰状的激发,这是典型的无序材料。观测结果与热容测量结果一致。
