Andrew V. Teplyakov

Andrew V. Teplyakov is a Professor in the Department of Chemistry and Biochemistry at the University of Delaware's College of Arts & Sciences, where he leads research in surface and interface science with applications in semiconductor manufacturing and nanomaterials development.

Education:

• B.S. in Chemistry, Moscow State University (1992)
• M.S. (1993)
• Ph.D. in Chemistry, Columbia University (1997)
• Postdoctoral Fellow, New York University (1997-1998)

Professor Teplyakov's research bridges physical, organic, and inorganic chemistry to solve molecular-level problems in thin film growth, etching, and nanomaterial formation. His group employs vibrational spectroscopies, electron spectroscopies, mass spectrometry, and computational methods to study chemical transformations on semiconductors. Current projects focus on atomic layer deposition (ALD) and etching (ALE) for semiconductor applications, covalent attachment of nanoparticles, and defect engineering for solar cells, emphasizing atomic-scale precision.

Analysis of his 2023-2025 publications reveals dominant themes in area-selective atomic layer processes for semiconductor manufacturing, with significant contributions to solar cell passivation and magnetic material engineering. His work consistently connects fundamental surface chemistry to industrial applications through molecular-level control.

Professor Teplyakov directs the Teplyakov Research Group, which develops novel surface modification techniques and investigates covalent binding mechanisms for fullerenes and nanoparticles. The group maintains strong industry and national laboratory collaborations to advance atomic-scale manufacturing capabilities for next-generation electronic and energy devices.
