DEVELOPMENT OF PHONON MEMORY USING ORGANIC ULTRA-THIN FILMS

我们用非弹性电子隧道谱(IETS)研究了有机超薄膜的基本现象。结果为高密度记录系统提供了有价值的信息。[1]在二乙炔单体膜中观察到与分子吸附和聚合相对应的IETS。2)IETS图案的变化可以通过电压脉冲来控制。[2]在TCNQ/TMPD吸附LB膜中获得了与TCNQ和TMPD之间的电荷转移相对应的IETS。4)在电压脉冲下观察到IETS的显著变化。5)IETS的可逆变化。基本的实验结果显示了一种新的基于IETS和STM针尖的高密度记录系统的潜力。

We have investigated the basic phenomena in organic ultra-thin films using inelastic electron tunneling spectroscopy (IETS). The results provide valuable information for highdensity recording system.[1] IETS in diacetylene monomer films1) IETS corresponding to the molecular adsorption and polymerization is observed.2) Chenge of IETS patterns can be controlled by the voltage pulses.[2] IETS in TCNQ/TMPD adsorption LB films3) IETS corresponding to the charge transfer between TCNQ and TMPD is obtained.4) A marked change of IETS by voltage pulses is observed.5) A reversible change of IETS is also observed.The basic experimental results show the potential of a new high-density recording system using IETS and STM tip.
