Alkylbenzene, normal alkanes and alkylcyclohexane on the pyrolysates of P. Boryanum at 300℃ had uniform distribution and the relative content of them was similar, indicating that they originated from same precursors. Fatty acids, alcohol and ketone in algal cell are the possible precursors. For example, the precursor of relatively abundant C〓 alkylbenzene and alkylbenzene with C〓 side chain perhaps related with palmitic acid. N-alkylnaphthalene in pyrolysates at 300℃ probably derived from alkylation of cleavage products of aromatic steranes and terpanes.

With the dose of 7.04 mC/cm2, ODT/Au will become a more strengthened structure and then form a negative resist in the correlation with cross-linking from alkyl matrix, partial breakdown of S-Au bonding and surface adsorption by air-borne species. Thus, it can obtain a gold pattern via gold-etching process. Besides, as a result of massive breakdown of alkyl matrix and S-Au bonding from ODT/Au under irradiation with doses of 64.06 and 128.13 mC/cm2, ODT SAMs would form a loose-packed structure on the gold substrate. The ODT/Au becomes less resistive for gold-etching and a positive gold pattern would form after gold-etching.

结果发现：以50 eV 低能量电子在照射剂量7.04 mC/cm2微影并曝露於大气后，受到来自於ODT/Au碳链间的交联、部分的S-Au键结破坏以及照射后立即曝露大气所吸附於表面的碳氧化物种的共同影响下，ODT SAMa於Au膜基材上将形成更紧密复杂的结构而作为负型阻剂，经后续湿式蚀刻15分钟后将显影出来Au的负型图案；当提升照射剂量至64.06及128.13 mC/cm2后，由於ODT/Au上碳链及S-Au键结的大量破坏，将使ODT/Au结构不能稳固且紧密地排列於Au膜基材上，显影时Au蚀刻液将容易穿过ODT SAMs抵达S/Au界面而移除Au，而形成正型图案。
