dc.description.abstractINTEGRATION OF THE ORGANIC MOLECULAR FUNCTIONS INTO THE SEMICONDUCTORS WITH A HIGH SELECTIVITY AND ORDERING HAS BEEN AN ESSENTIAL CORNERSTONE FOR FABRICATING THE MOLECULAR ELECTRONICS. THIS STUDY FOCUSED ON THE SELECTIVE ADSORPTION OF METHYL OXIRANE AND BUTADIENE MONOXIDE ON SI(111)-(7?7), ALSO THE SURFACE ORDERING OF 1-PROPANETHIOL ON SI(111)-(7?7) AND DIACETYL ON GE(100). OUR STUDIES SHOW THAT METHYL OXIRANE (C3H6O) ADSORBS ON SI(111)-(7?7) VIA THE COMBINATION OF DATIVE-BONDED ADDITION AND RING-OPENING REACTION. BUTADIENE MONOXIDE (C4H6O) IS FOUND TO UNDERGO A [2+2]-LIKE CYCLOADDITION THROUGH C=C BOND. THE DIFFERENT REACTION MECHANISMS OF THE TWO EPOXIDE MOLECULES ARE ATTRIBUTED TO THAT THE SUBSTITUTED VINYL GROUP PLAYS AN IMPORTANT ROLE IN DIRECTING THE SURFACE REACTION PATHWAY. THE WELL-DEFINED MOLECULAR NANOCORRALS HAVE BEEN FABRICATED BY DISSOCIATIVE ADSORPTION OF THE 1-PROPANETHIOL (C3H8S) MOLECULES ON SI(111)-(7?7) BY CAREFULLY ADJUSTING EXPERIMENTAL TEMPERATURE.
