Marian Tzolov

Marian Tzolov is a Professor of Physics in the Department of Physical and Environmental Sciences at Commonwealth University of Pennsylvania (Lock Haven campus). His primary affiliations are with this institution, where he actively teaches and conducts research.

Research Expertise: Professor Tzolov's research spans several interconnected areas of solid-state physics and materials science. Key domains include:

• Nanotechnology & Materials: Synthesis and characterization of nanomaterials (carbon nanotubes, nanoparticles, thin films), with a focus on zinc oxide (ZnO), amorphous silicon-carbon alloys (a-SiC), and polymer semiconductors (e.g., PPV).
• Optoelectronics & Photonics: Development and analysis of devices like infrared photodetectors (using PbS/carbon nanotubes or CNT-Si heterojunctions), solar cells (microcrystalline silicon), and light-emitting devices.
• Spectroscopy & Characterization: Extensive use of Raman spectroscopy, optical spectroscopy, and electron microscopy for probing material properties, including vibrational modes, electronic transport, and surface effects.
• Deposition Processes: Expertise in RF magnetron sputtering and very high-frequency glow discharge for thin-film fabrication.

Publication Trends: Analysis of Professor Tzolov's 10 most recent publications reveals a consistent focus on the fundamental physics and applications of nanostructured materials and thin films. Early work (1990s) centered on characterizing amorphous semiconductors (Si, SiC, ZnO) and polymer films. Since the early 2000s, his research prominently features carbon nanotubes, exploring their electronic transport, heterojunction formation with silicon, and applications in infrared detection and imaging (e.g., novel SEM scintillators). The work demonstrates a strong experimental approach combining materials synthesis/fabrication with detailed optical and electronic characterization.

Teaching: Professor Tzolov is responsible for core physics courses including Electronics, Introductory Physics, and Thermodynamics/Statistical Physics. He has also developed and teaches a specialized course in Modern Optoelectronics, reflecting his research expertise. No specific information about advised students is provided.
