You can use Web of Science to find the more cited articles for most Science/Technology disciplines.
First Step: Search Web of Science for your area. Be sure to limit your search by date, you want to get the current leaders.
Then you change the sort system from by publication date to Times Cited -- highest to lowest
If need be, narrow your results by discipline, if you have an interdisciplinary topic, you can remove other areas from your results.
When you have found the most cited articles in your fields, you can check the authors to see what else they have written or so you can stalk them in other places.
