论文摘要
纳米量表上的能量吸收对于许多生物和化学系统至关重要。我们在这里报告说，与正常散装水的情况相比，在短红外脉冲的辐射下，限制在碳纳米管中的水分子可以实现两倍的吸收效率。发现因（6,6）碳纳米管引起的限制效果非常强大，相当于5 $ v/nm $的静态电场。这些发现不仅在设计高效率纳米设备的情况下具有启发性，而且还可以理解生物学渠道的行为。
The energy absorption on nanometer scale is vital for many bio and chemical systems. We report here that a two times amplification in absorption efficiency can be achieved by water molecules confined in carbon nanotubes with small radius, compared with situations in normal bulk water, under irradiations of short mid-infrared pulses. The effect of confinement due to a (6,6) carbon nanotube is found to be very robust, equivalent to that of a 5 $V/nm$ static electric field. These findings are instructive not only for designing high-efficiency nano devices but also for understanding behaviours in biological channels.
